Třeboň is a picturesque spa town located in the South Bohemian Region of the Czech Republic, specifically within the Jindřichův Hradec District. With a population of around 8,300 residents, it is nestled in a gently undulating landscape near the Austrian border, positioned between the cities of České Budějovice and Jindřichův Hradec. Often called the "pearl of South Bohemia" or the "town of lakes," Třeboň is renowned for its blend of historical architecture, natural beauty, and a long-standing tradition of fish farming, particularly carp. The town's historic center is a protected urban conservation area, featuring Renaissance and Baroque elements that reflect its medieval roots.
Třeboň Castle (Zámek Třeboň / State Chateau Třeboň)
The main
landmark of the town is the Renaissance Třeboň Castle, built on the site
of an earlier 14th-century Gothic structure. A small stone castle was
first mentioned in 1374. After a major fire in 1562 damaged the town,
Vilém of Rosenberg ordered its reconstruction into a grand Renaissance
chateau (completed around 1565–1575). His brother, Petr Vok of Rosenberg
(the last male of the line), made it his primary residence and a center
of cultural and political life.
The castle features:
Opulent
Renaissance interiors with period furnishings, an alchemist’s
laboratory, Kunstkammer (cabinet of curiosities), and women’s quarters
(Fraucimor).
More restrained Schwarzenberg-era private rooms from the
19th–early 20th centuries (the family owned it from 1660 until after
WWII).
Guided tours covering stables, a dog kitchen, and underground
casemates (passages linked to the town’s fortifications).
Adjacent is a beautiful English-style park with a music pavilion known
for its acoustics. The castle also houses exhibits on the noble families
and serves as a cultural venue. It is one of the most visited sites and
offers a contrast between Renaissance splendor and later
Baroque/19th-century modifications.
Masaryk Square (Masarykovo
náměstí) and Town Hall
The picturesque central square is the heart of
the old town, lined with colorful burgher houses featuring Renaissance
and Baroque facades. Key elements include:
A Renaissance stone
fountain from 1569.
A Baroque Marian Column.
The Old Town Hall
(built 1563), with a prominent 31-meter (102 ft) quadrangular tower
added in 1638 that offers panoramic views.
The square is lively
with cafes and shops, making it an ideal spot for people-watching and
soaking in the medieval atmosphere.
Church of Our Lady Queen and
Saint Giles (Chrám Panny Marie Královny a Sv. Jiljí)
This Gothic
church, part of the former Augustinian Monastery founded in 1367 by the
Rosenbergs, dominates the skyline near the square. Construction began
the same year as the monastery. It is the largest building in the
monastic complex (the monastery was dissolved in 1785). Its architecture
and interior make it a highlight of the town’s sacred landmarks.
Town Fortifications and Gates
Třeboň was fortified around 1300 and
strengthened in the late 14th century. Fragments of the medieval walls,
along with several gates, survive:
Budějovická Gate
Novohradská
Gate
Hradec Gate (and others)
These, combined with the Svět
Pond as part of the defenses, give insight into the town’s strategic
importance.
Schwarzenberg Tomb (Schwarzenberg Mausoleum)
Located south of the town in a park setting, this impressive neo-Gothic
structure from the 19th century serves as the final resting place for
members of the powerful Schwarzenberg family. It is a striking
architectural monument and popular photo spot.
The Fishpond
System and Natural Landmarks
The Třeboň Basin’s fishpond network is
the town’s most distinctive feature and a masterpiece of Renaissance
engineering. Over 500 ponds cover thousands of hectares and date back to
the 13th–16th centuries. Key highlights:
Svět Pond (201 ha / ~500
acres): Adjacent to the town, it forms part of the historic
fortifications and is used for recreation (swimming, boating) as well as
fish farming.
Rožmberk Pond (489 ha / ~1,210 acres): The largest
fishpond in the Czech Republic and one of the largest in the world,
built 1584–1590 by Jakub Krčín. Its massive dam (2.5 km long) is lined
with ancient oak trees.
Engineering marvels include the Zlatá
stoka (Golden Canal), a ~45 km water supply system with a minimal
gradient, and the Nová řeka (New River), a canal diverting the Lužnice
River. These works, developed under pond masters like Štěpánek Netolický
and Jakub Krčín, transformed marshy land into a productive aquaculture
region.
The area is a UNESCO Biosphere Reserve (since 1977) and on
the tentative World Heritage list for its cultural landscape,
biodiversity (rich birdlife, wetlands), flood control, and ongoing
traditional carp farming. Hiking and cycling trails circle the ponds,
offering scenic views.
Brief History and Geography
Třeboň dates to the 12th century and
gained importance under the Rosenberg (Rožmberk) family in the 14th–17th
centuries. They developed the fishpond system, with key figures like
Jakub Krčín building major ponds such as Svět (World) and Rožmberk. The
latter remains one of the largest fishponds in the world at ~489
hectares.
The Schwarzenberg family later owned the town and castle
from 1660. The historic center features preserved Renaissance and
Baroque buildings, town walls, gates, and an English-style park. The
surrounding Třeboňsko Protected Landscape Area includes ponds, peat
bogs, forests, and dikes—ideal for outdoor activities.
Geography
note: Flat terrain makes it very walkable and bike-friendly. The Svět
pond borders the town, and larger ponds like Rožmberk lie nearby.

Topography and Relief
The Třeboň Basin, in which the town is
centrally located, is a structural depression covering roughly 1,360
square kilometers with an average elevation of 457 meters. This basin
features a varied relief: the central areas are predominantly flat,
ideal for the development of wetlands and ponds, while the eastern parts
transition into flat hilly terrain, and the western edges form an
asymmetrical ridge with more rugged, hilly features. The underlying
geology consists of heavy impermeable clays, which have facilitated the
accumulation of peat deposits in extensive bogs surrounding the town.
These bogs, rich in peat, have historically supported the establishment
of a renowned peat spa in Třeboň, leveraging the natural resources for
therapeutic purposes. The overall landscape is gently rolling, with
subtle elevations that rarely exceed modest hills, creating a serene,
low-lying environment interspersed with forests and meadows.
Hydrography
Water dominates the geography of Třeboň, making it one of
the most hydrologically unique areas in Central Europe. The town and its
basin are renowned for an intricate system of artificial fishponds,
constructed since the Middle Ages to transform flood-prone marshlands
into productive aquaculture sites. Key among these is the Rožmberk Pond,
the largest in the Czech Republic and the world's largest fishpond,
spanning 489 hectares and built between 1584 and 1590. Adjacent to the
urban area is the Svět Pond, covering 201 hectares, which serves dual
purposes in fish farming and recreational activities like water sports.
The Lužnice River, a major waterway, flows through the eastern part of
the territory, providing essential water supply to Rožmberk and other
ponds via a network of smaller tributaries and canals. A notable
engineering feat is the Zlatá stoka (Golden Canal), a medieval waterway
that channels water from the Lužnice to sustain the pond system,
exemplifying centuries-old hydraulic management. In total, the basin
hosts hundreds of ponds, some as large as small lakes, which not only
support a thriving carp-fishing economy but also regulate local flooding
and maintain biodiversity. Additionally, sandpit lakes in areas like
Suchdol, Halámky, and Veselí add to the region's freshwater systems,
formed from former mining sites and integrated into the natural
hydrology.
Climate
Třeboň experiences a temperate continental
climate, characteristic of Central Europe's inland regions, with
moderate influences from its basin setting and elevation. Summers are
typically warm, with average high temperatures around 23–25°C (73–77°F)
in July, while winters are cold but not extreme, with January lows
averaging -3 to -5°C (23–27°F). Precipitation is evenly distributed
throughout the year, totaling about 600–700 mm annually, supporting the
lush wetlands and peat bogs. The basin's low-lying topography can lead
to fog and higher humidity, especially in autumn, enhancing the misty,
atmospheric quality of the landscape. This climate fosters the growth of
peat moss and sustains the pond ecosystems, though it also contributes
to occasional flooding risks managed by the engineered water systems.
Natural Features and Environment
The natural environment of
Třeboň is defined by its wetlands, peat bogs, and oak-lined dikes that
border the ponds, creating a mosaic of habitats. The entire municipal
territory falls within the Třeboňsko Protected Landscape Area, a
UNESCO-recognized biosphere reserve that emphasizes conservation of the
unique pond landscapes, wild meadows, pine woods, and Baroque-era
villages. Biodiversity is high, with the area serving as a haven for
waterfowl, amphibians, and aquatic plants, alongside forested zones that
provide habitats for deer and other wildlife. The peat bogs, formed over
millennia on the impermeable clay base, are a key ecological feature,
storing carbon and supporting specialized flora like sphagnum moss.
Environmental efforts focus on sustainable fish farming, peat extraction
for spas, and tourism that balances human activity with preservation,
making Třeboň a model for integrated landscape management in Europe.
The name Třeboň most likely comes from the word refine
or need, which means to breed, improve or perfect (see the meaning
of the word refined). The soil was sown here through felled trees.
Almost the entire Třeboň region was originally forested and
waterlogged (floodplain forests), and trees have been mined and
processed here since the beginning of settlement; country resp. the
soil was sifted / needed for economic use. Similarly, it got the
names of the village Třebonín, Třebíč, Třebenice, Třebová,
Třebichovice, Třebechovice, Třebušín, etc. (some sources state the
meaning of the word Třebíč as felling or destroying the forest).
The beginnings of the town date back to the middle of the 12th
century, when a court and then a settlement were established on the
site. Around 1280, the parish church in Třeboň (Witingenowe) is
mentioned. The status of the town of Třeboň was granted in 1341 and
in 1376 and 1378 the so-called right of royal towns and the
privilege of importing salt. It was originally owned by the Vítkovci
family (Vítek z Prčic), in 1366 it passed under the auspices of the
brothers from Rožmberk and got its Czech name. In 1367, the four
Rosenberg brothers founded an Augustinian monastery in Třeboň, which
became the center of education of the whole area (it was abolished
by Emperor Joseph II in 1785, the monastery premises then belonged
to the Třeboň vicariate). The Prince's Brewery in Třeboň was founded
in 1379. Towards the end of the 14th century, fortifications were
built around the town with walls and a moat, which proved successful
in the Hussite wars, and transformed Třeboň into an impregnable
fortress capable of resisting many attacks.
The first ponds
were founded at the end of the 15th century by Štěpánek Netolický.
His work in the 16th century was followed by pond fishermen Mikuláš
Ruthard from Malešov and Jakub Krčín. In the 1680s (under the owner
Vilém of Rožmberk), Edward Kelley had an alchemical workshop at
Třeboň Castle. After the death of his brother Vilém, the Rosenberg
ruler Petr Vok of Rožmberk moved his seat to Třeboň, who died here
in 1611 without heirs. The manor belonged to the Švamberks and after
the battle on Bílá hora to the emperor. In 1660, the Eggenberg
estate of Třeboň became the property of the Schwarzenberg princely
family, who administered it until the first land reform of 1919 (the
chateau until 1940 and 1948, respectively). In 1779, a Catholic
vicariate was established here, which existed until 1952. In the
middle of the 19th century, teacher Václav Hucek and his daughter
Berta founded the first peat spa near the peat bog in the immediate
vicinity of Zlatá stoka. The President of the Republic T.G. Masaryk
officially visited the city twice, in 1919 and 1925.
During
World War II, over 80 citizens of Třeboň laid down their lives. On
June 26, 1942, the Gestapo executed the pre-war mayor, František
Adam. The names of the victims are listed on a plaque in the park in
front of the primary school building. Třeboň was liberated on May 9,
1945 by the troops of the 9th Guards Army of the 2nd Ukrainian Front
of the Soviet Army.
From the middle of the 19th century,
Třeboň developed as a full-fledged district town, ie the seat of a
political and judicial district. In 1960, however, during the
nationwide reorganization of the state administration, the Třeboň
district was abolished and the town was granted spa status. The Na
Sadech primary school was established in the building of the former
district office with a turret. In 1960, the Třeboň Department of the
Institute of Microbiology of the ASCR was established. On Wednesday,
August 21, 1968, the Main (Masaryk) Square was occupied by Soviet
occupation tanks.
Culture and Economy
Třeboň's culture revolves around its aquatic heritage, with annual carp-harvesting festivals in autumn featuring traditional draining of ponds, fishing demonstrations, and feasts. Local cuisine emphasizes freshwater fish, particularly Třeboň carp, often prepared grilled or in soups, alongside Bohemian beers from the Regent Brewery. The economy is driven by tourism, spa services, agriculture (especially aquaculture), and small-scale brewing. The town hosts events like music festivals and markets, fostering a community vibe. Sustainability is key, with eco-tourism promoting cycling and birdwatching in the protected wetlands. Overall, Třeboň embodies a harmonious mix of history, nature, and wellness, making it a tranquil escape from urban hustle.
