Tholen is a municipality in the province of Zeeland, southwestern Netherlands, encompassing two peninsulas that were formerly islands: the larger Tholen to the south and the smaller Sint Philipsland to the north. With a population of around 26,000, it is known for its maritime heritage, historical town center, and role in the Delta Works flood protection system, blending rural tranquility with coastal accessibility. The administrative center is the town of Tholen, a compact historical settlement partly encircled by a canal (gracht) and bordered by a harbor for fishing and yachts. Situated approximately 30 km southeast of Rotterdam, Tholen's landscape reflects centuries of land reclamation, making it a quintessential example of Dutch ingenuity in managing water-dominated environments.
Tholen has a historic city center, which is still
largely surrounded by walls and vests. The city center is also
partly bordered by a harbor. The area within the fortresses has been
a protected cityscape since 1991, making it one of the protected
city and village views in Zeeland. Furthermore, the city has dozens
of national monuments.
The cityscape is dominated by the
Grote or Onze-Lieve-Vrouwekerk, a cross basilica in the Brabantine
Gothic style, possibly designed by Everaert Spoorwater, a Brussels
master builder who was often involved in the construction of
churches in this style in the Netherlands. Construction of the
church started in about 1404. On the site of the current nave, the
church had a predecessor of unknown construction date that was
demolished around 1360. The tower is 49 meters high and the base is
a pure square of 8.50 meters. The radiating chapels of the choir
have never been finished, but the foundations have been laid and a
wall extension is visible on the outside of the north choir. A
striking detail: the outer columns of the choir church were
therefore once built as inner columns.
A striking building is the
former town hall of Tholen from the 15th century, which was designed
by members of the famous Keldermans family of architects. In this
town hall hangs the oldest carillon clock in the Netherlands, also
from the 15th century.
The cityscape is further determined by two
windmills within the city center, De Hoop, which is built on one of
the walls, and the De Verwachting windmill, which was completely
restored in 2009.
A historic building is also the rebuilt
Gasthuiskapel.
On the Markt is the Roman Catholic Church of Our
Lady of the Assumption from the early 20th century.
There are a
number of interesting houses in the historic city center. One of the
oldest is De Twee Stoven at Stoofstraat 5-7, built in 1622. Also at
Markt, Kerkstraat, Bakstraat, Brugstraat and Hoogstraat are some old
houses, which sometimes have a stepped gable.
A former salt shack
is located at Contre Escarpe 1. Salt was extracted here until 1901.

Prehistory and Early Settlement (Pre-12th Century)
The earliest
traces of human habitation in the Tholen area date to around the
beginning of the Common Era, with archaeological finds indicating sparse
settlement in what was then a delta landscape of mudflats and small
islands. The region, part of the Scheldt estuary, was shaped by natural
silting and early human efforts to manage water. By the 12th century,
the area consisted of several small islands off the Brabant coast,
including Schakerloo, which formed the core of modern Tholen. These
islands emerged through natural processes and initial diking, setting
the stage for medieval development.
Medieval Origins and Growth
(12th–14th Centuries)
Tholen's formation accelerated in the 12th
century with the poldering (land reclamation) of salt marshes, merging
small islands into larger landmasses. The first documented mention
occurs in 1212, when the Duke of Brabant established a toll watch on
Schakerloo Island along a waterway between Antwerp and Holland. This
toll station was later moved to the dike of the
Vijftienhonderdgemetenpolder (diked before 1220) along the Eendracht
River, at a calm point where tidal currents met, facilitating safe
anchorage and trade. The settlement, initially called "Tolen" or
"Hardestock," is first named in a 1290 charter granting toll exemptions,
highlighting its growing economic role.
By the 13th century, Tholen
had developed into a village centered on toll collection, with the inner
town west of the sea dike (now Hoogstraat and Verbrandestraat). Lords
like Jan van Beaumont and the Counts of Holland and Zeeland granted
privileges, including salt production and, in 1380, the construction of
madder kilns for processing Rubia tinctorum roots into red dye powder—a
key industry until synthetic dyes in the late 19th century. In 1365,
amid conflicts with the Lord of Bergen op Zoom, Jan van Blois hastened
the digging of moats for defense. The following year, 1366, Tholen
received city rights, formalizing its status with a medieval street
grid, star-shaped fortifications, and walls that remain preserved as
national monuments today. By the mid-15th century, after further
poldering reached the island's limits, Tholen was at its medieval peak
as a trading hub.
15th Century: Disasters and Reconstruction
A
major setback occurred on May 16, 1452, when a fire destroyed
five-sixths of the town, including the hospital, town hall, and gates.
Reconstruction followed swiftly: the current town hall and hospital
chapel date to around 1460, with walls and gates rebuilt. In 1458, the
Netherlands' oldest carillon was installed in the Dutch Reformed Church
(a Brabantine Gothic structure with a 49-meter tower), expanded in 1627
to chime every 15 minutes. Despite these efforts, economic conditions
remained precarious amid ongoing floods and regional tensions.
16th Century: Eighty Years' War and Reformation
The 16th century
brought turmoil. Tholen was pawned to the Lord of Bergen op Zoom in the
early 1500s, temporarily losing its seat in the States of Zeeland.
Frequent storm floods ravaged Zeeland, and during the Eighty Years' War,
the island was plundered by Spanish forces and Geuzen rebels. As the
last Zeeland city to switch sides, Tholen joined the Prince of Orange in
1577. The Reformation followed in 1578, adapting the Church of Our Lady
for Protestant worship, secularizing church goods, and expelling
Catholic clergy; the first Protestant minister officiated that autumn.
With Brabant under Spanish control, defenses were bolstered: city walls
were upgraded around 1600 with seven bastions and moats, while forts and
redoubts lined the Eendracht. Dikes were breached for flooding as a
defensive tactic. In 1588, this strategy repelled an attack by the Duke
of Parma's army attempting to cross the Eendracht.
17th–18th
Centuries: Economic Stability and Declining Fortifications
Post-Eighty Years' War, Tholen's defenses deteriorated due to neglect
and natural disasters, such as the 1682 flood that destroyed Fort
Nassau. In 1712, a French raiding party surprised and plundered the
town. Agriculture remained the economic foundation, supplemented by
grain markets (twice yearly), a fat cattle market (1618), and a lean
cattle market (1731). After Reimerswaal's abandonment in 1631, its
refugees settled in Tholen, boosting mussel and oyster fishing. The 1736
construction of Windmill De Hoop (a corn mill on the city walls, later
heightened by 5 meters) marked cultural development. Governance involved
two burgomasters and eight aldermen, with the last sword execution in
the town hall square in 1750. Political factions clashed, including
State- and Prince-supporters in 1672, 1702, and 1747, and a 1787
garrison mutiny against Patriots.
19th Century: De-Fortification
and Industrialization
After the French departure in 1813, Tholen's
fortress status was abolished in 1814, leading to the demolition of
gates and buildings. Walls were transformed into parks in the mid-1800s.
Oyster culture boomed, with Tholen supplying one-sixth of Dutch mussels;
the harbor filled with hoogaars boats. Modernization included a gas
factory in 1864 (operating until after WWII). Population grew steadily
from nearly 2,000 in 1798, though it dipped pre-WWII. Religious
diversity expanded: Catholicism revived in 1795, using the Walloon
church from 1818; a Christian Seceded congregation formed in 1851.
20th Century: Wars, Reclamation, and Modernization
The 1928
Eendracht bridge ended isolation, financed locally despite Tholen's
small size (~3,100 inhabitants). During WWII, the bridge was destroyed
twice (1940 by Dutch forces, 1944 by retreating Germans), and occupiers
flooded the island in 1944, evacuating most residents except in Tholen
town. Post-war, population rebounded with new districts like Dalempolder
and Molenhoek. The harsh 1962–1963 winter, Scheldt-Rhine Canal (1975),
and Delta Works decimated fishing by altering salinity. The 10.5-km
Oesterdam (1988), part of post-1953 flood defenses, connected Tholen to
Zuid-Beveland, shifting ecosystems from saline to freshwater. Industry
attracted from 1960, with business parks north of town.
Administratively, Tholen was independent until July 1, 1971, when it
merged with surrounding municipalities (Oud-Vossemeer, Poortvliet, etc.)
into the modern municipality. Sint Philipsland joined in 1995. A new
town hall opened in 2008. Since 1994, Tholen has twinned with Iława,
Poland.
Tholen occupies a low-lying area in the Zeeland archipelago, with
coordinates centered at 51°32′N 4°12′E and an average elevation of -1
meter below sea level, typical of the region's vulnerability to
flooding. The municipality spans 254 km², including 147 km² of land and
107 km² of water, forming a double peninsula bounded by major waterways:
the Scheldt-Rhine Canal (formerly the Eendracht) to the east, the
Oosterschelde estuary to the south, the Keeten-Mastgat straits to the
west, and the Krammer strait to the north. The two peninsulas are
separated by the Krabbenkreek, a former strait now a bay due to
reclamation. The terrain features polders—reclaimed lowlands protected
by dikes—interspersed with canals, rivers, and tidal inlets, supporting
agriculture and wetlands. Notable infrastructure includes the 10.5 km
Oesterdam (Oyster Dam), the longest in the Delta Works, connecting
Tholen to Zuid-Beveland and converting saltwater to freshwater
environments. The Bergse Diepsluis lock, built on the ruins of the
drowned medieval city of Reimerswaal, facilitates maritime traffic.
Tholen experiences a temperate maritime climate, with mild summers
(average highs of 21–23°C in July) and cool winters (average lows of
1–3°C in January), influenced by the North Sea. Annual precipitation
averages 800–900 mm, distributed evenly but with occasional heavy rains
leading to flooding risks, mitigated by dikes. Winds are often strong,
particularly from the southwest, contributing to a partly cloudy sky
year-round. The area's hydrology has shifted from saline to freshwater
due to dams, affecting local ecosystems like oyster beds, now historical
remnants. Biodiversity includes waterfowl in bays and agricultural
fields supporting crops like potatoes and grains.
As of 2021, Tholen's population was 26,085, with a density of 178 inhabitants per km². By 2024, the borough of Tholen town itself had grown to 8,420 from 7,545 in 2013, an increase of about 12%. The population is predominantly Dutch, with residents known as Tholenaars. Settlements include seven on Tholen Island (e.g., Tholen town, Sint-Maartensdijk, Poortvliet) and three on Sint Philipsland (e.g., Sint Philipsland village). The area attracts retirees and commuters due to its proximity to Rotterdam, with a stable, aging demographic influenced by rural lifestyles.
Tholen's economy revolves around agriculture, maritime activities, and tourism. Polder farmlands produce crops like grains and vegetables, while the harbor supports fishing (historically oysters) and yachting, with a marina and historic shipyard. The Scheldt-Rhine Canal enables trade and logistics, connecting to major ports. Tourism draws visitors to historical sites, cycling routes, and water sports, boosted by the Delta Works' engineering marvels. Small-scale industries include milling at De Hoop and local crafts.
