The Old Town Hall (Czech: Staroměstská radnice, also known as the Staroměstská radnice with Astronomical Clock) stands as one of Prague’s most enduring symbols of civic self-governance and Czech national identity. Located on the eastern side of Old Town Square (Staroměstské náměstí), it is a complex of interconnected medieval houses rather than a single planned structure. Its history spans over 680 years, encompassing architectural evolution from Romanesque foundations through Gothic, Renaissance, and Neo-Gothic phases, pivotal political events, legendary folklore, and dramatic 20th-century destruction. Today it forms part of Prague’s UNESCO World Heritage site, serving as a tourist attraction, wedding venue, exhibition space, and observation tower while preserving its role as the oldest town hall in Bohemia.
Origins and Foundation (12th–14th Centuries)
The site’s roots
trace to the 12th–13th centuries, when Romanesque merchant houses formed
the core of what became the Old Town. Their cellars and ground floors
survive in the current basements, including a two-room Romanesque hall
in the “Cockerel” (U kohouta) house dating to around 1200. These
structures originally served commercial purposes along trade routes.
In 1338, under King John of Luxembourg (John the Blind), the councillors
of the Old Town purchased a large two-storey patrician house belonging
to the Volflin (Wolflin of Kámen) family—already about 200 years old at
the time. This marked the official founding of the Old Town Hall as the
seat of municipal administration, the first such institution in Bohemia.
The burghers adapted the house for governance and immediately began
expansions. Construction of a massive square-plan stone tower began
around 1340 on the western side; at 69.5 metres (about 228 feet), it was
the tallest structure in medieval Prague. The tower was completed in
1364 and has remained largely unchanged since. A Gothic stone portal
with mouldings on the western façade is one of the few visible remnants
of the original Volflin house.
Inside the tower, on the first floor,
a Gothic chapel dedicated to the Virgin Mary was built and consecrated
in 1381. Its pentagonal bay window, richly decorated with plastic motifs
(human faces, animals, and emblems of King Wenceslaus IV, including
kingfishers and the letter “E” for his queen Euphemia), is one of the
finest examples of late-14th-century Bohemian Gothic. The chapel served
as the spiritual heart of the complex and remains accessible today.
The Astronomical Clock (Orloj) – Installed 1410
The hall’s most
famous feature, the Astronomical Clock (Pražský orloj), was installed on
the southern wall of the tower in 1410. Clockmaker Mikuláš of Kadaň and
astronomer Jan Šindel (or Professor Jan Šindel) created the original
mechanism. It already displayed the core astronomical functions that
survive today. Extensive reconstruction and perfection occurred around
1490 by master locksmith Jan Růže (Hanuš of Růže). A popular
19th-century legend (popularised by writer Alois Jirásek) claims the
councillors blinded Hanuš to prevent him building a rival clock; in
revenge, he allegedly damaged the mechanism. In reality, the clock
stopped in 1865 and was saved from removal by watchmaker Ludvík Hainz.
The clock comprises three main parts:
Astronomical dial (upper):
Shows Central European time (added post-1948), Old Bohemian time (from
sunset), Babylonian/unequal hours (longer in summer), and sidereal
(star) time. It is the only surviving medieval clock capable of
displaying unequal hours.
Calendar dial (lower): Features allegories
of the months painted by Josef Mánes in 1865 (original in the City of
Prague Museum; current is a 1946 copy by Bohumil Číla).
Moving
figures: Every hour (9 a.m.–11 p.m.), the 12 Apostles process through
windows above the dials. Flanking figures include a skeleton (Death)
ringing a bell, a Turk (vanity/lust), a miser shaking a bag, and Vanity
admiring himself in a mirror. A rooster crows at the end.
The
apostles were destroyed in 1945 and replaced in 1948 by woodcarver
Vojtěch Sucharda. The mechanism, housed in a stone chamber behind the
façade, remains largely original and is one of the oldest continuously
operating astronomical clocks in the world.
Medieval and Early
Modern Expansions (15th–17th Centuries)
Construction paused during
the Hussite Wars (1419–1434). In 1458, the Mikeš house was added to the
west, enabling major interior work. The Old Council Chamber (still
largely preserved) dates to around 1470, with a late-Gothic wooden
coffered ceiling (polychromed in the 16th century), gilded chains added
in 1638, Gothic panelling, guild coats of arms, and a 15th-century
wooden sculpture of the Suffering Christ (“Ecce Homo”) inscribed “Judge
justly, O sons of man.”
Key historical events unfolded here:
1458: Bohemian nobles elected Jiří of Poděbrady (George of Poděbrady)
King of Bohemia in the Jiřík Hall (named after him).
1621: After the
Battle of White Mountain, 27 Czech Protestant leaders were imprisoned in
the hall before their execution on the square outside (commemorated by
27 white crosses in the pavement).
Renaissance modifications
transformed the south façade: a Late Gothic portal (late 15th century)
with ogee arch and finial; a Renaissance window (1520s) inscribed “Praga
caput regni” (“Prague, capital of the kingdom”); and sgraffito
decorations on the “Minute” (U minuty) house (early 17th century,
revealed in 1905). The complex grew by absorbing adjoining houses,
creating its irregular, organic appearance.
18th–19th Century
Unification and Neo-Gothic Remodelling
In 1784, when the four
historic Prague towns merged into one municipality, the Old Town Hall
became the seat of unified city administration. Architects including
Matěj Hummel, Petr Nobile, Pavel Sprenger, Bernard Grueber, Jan Bělský,
and Bedřich Münzberger oversaw modifications.
The 19th century
brought the most visible changes:
1835: Purchase and Empire-style
renovation of the Cockerel house.
1840s: Construction of a new
Neo-Gothic east wing (replacing earlier structures) and northern
additions.
1879–1880: Neo-Renaissance remodelling of the Mikeš house
by Antonín Baum.
1896: Addition of the Minute house.
Weddings have
been held here since 1871.
Interior highlights from this era
include mosaics by Mikoláš Aleš (1936–1939) depicting Libuše’s prophecy
and “Slavdom’s Homage to Prague,” paintings by Václav Brožík (Jan Hus at
Constance and the 1458 election), and a bronze Lumír and Song by Josef
Václav Myslbek.
World War II Destruction and Post-War Recovery
(1945–Present)
The hall’s darkest chapter came during the Prague
Uprising against Nazi occupation. Its basement served as headquarters
for the Czech National Council. On 7–8 May 1945 (literally the last days
of the war in Europe), German forces shelled and set the building
ablaze. The entire Neo-Gothic east and north wings were destroyed, along
with the public hall, parts of the chapel, the archive, library, and
many collections. The 12 Apostles figures burned; the tower and clock
suffered heavy damage but survived. The elevator installed in 1927 was
preserved and later moved to the National Technical Museum.
The ruins
were cleared but the east wing was never rebuilt—leaving an open space
with memorial plaques and a grille (added 1975 for the 30th anniversary
of liberation, designed by architect J. Koreček and sculptor J. O.
Lankáš). Multiple 20th-century architectural competitions for
reconstruction failed to produce a built result.
Today the
surviving south wing and tower form the complex visitors see. The tower
offers panoramic views via a modern lift (installed 2000). The
Romanesque cellars function as a dungeon exhibition. Ceremonial halls
host events, and the site remains a living monument.
Core Structure and Construction History
The complex originated in
1338 when the Old Town councillors, with permission from King John of
Luxembourg, purchased the Gothic corner house of the patrician Volflin
(or Wolflin) of Kámen (late 13th century, built on even earlier
Romanesque foundations visible in the basements). This became the
administrative heart. A massive square-plan prismatic tower (69.5 m /
228 ft high) was annexed to it and completed in 1364, making it the
tallest secular structure in medieval Prague. Further houses were
acquired and integrated westward and southward:
Mikeš House
(added 1458, west side; later Neo-Renaissance rebuild 1879–1880 by
Antonín Baum).
Cockerel House (“U kohouta,” bought 1835; retains
Romanesque hall ~1200 and Late Gothic upper floors).
Minute House (“U
minuty,” added late 19th century; early 15th-century Gothic core with
17th-century sgraffito facade).
South wing extensions and a
short-lived Neo-Gothic east/north wing (1840s, by Pietro Nobile and
Pavel Sprenger; destroyed 1945).
The original Volflin House
largely vanished through renovations, but a Gothic stone portal with
rich mouldings survives on the western facade — one of the few visible
remnants of the 14th-century core. The building’s footprint expanded
eastward until the 1945 Prague Uprising fire destroyed the Neo-Gothic
wings, leaving only a torso adjoining the tower. Today the surviving
south wing and tower present a harmonious Gothic-dominated street
frontage.
The Tower and Its Architectural Highlights
The tower
dominates the composition: a solid stone prismatic shaft rising to a
late-Gothic gallery and pyramidal roof with finials (restored after 1945
damage). Its lower levels blend seamlessly with the adjoining houses. On
the first floor, inside the tower body, sits the Chapel of the Virgin
Mary (consecrated 1381), one of the finest surviving examples of High
Gothic sacred architecture in a secular building. It features a
cross-vaulted aisle opening into a projecting pentagonal oriel (bay)
chapel — richly decorated with plastic sculptural elements (human faces,
animals, foliage) executed by royal stonemasons under Wenceslas IV. The
bay’s exterior is supported on slim columns ending in pinnacles; its
corner once held a Gothic Madonna statue (now a copy). Emblems above the
portal include kingfishers and the letter “E” (likely for Queen
Euphemia/Žofie). The chapel’s ogival arches, stained-glass windows, and
painted starry vault create an intimate, jewel-like space that feels
like a miniature cathedral embedded in civic stone.
The
Astronomical Clock (Orloj) — Architectural Integration
Mounted on the
southern tower wall (installed 1410 by clockmaker Mikuláš of Kadaň and
astronomer Jan Šindel; facade decorations and calendar dial refined
~1490 by Jan Růže/Hanuš), the clock is not merely a timepiece but a
Gothic-Renaissance sculptural masterpiece embedded in the masonry.
Late-Gothic slender columns and pinnacles frame the dials with figural
and floral plastic ornament. The astronomical (upper) dial sits within
an ornate Gothic canopy; below it, the calendar dial (original paintings
by Josef Mánes, 1865; current copy 1946) is surrounded by medallions.
Flanking sculptures include allegories of Vanity (mirror), Greed
(moneybag), Death (skeleton with bell and hourglass), and a Turk (lust),
plus the Archangel Michael. Every hour the upper windows open for the
procession of the Twelve Apostles (modern wooden figures by Vojtěch
Sucharda, 1948, replacing fire-damaged originals). The entire ensemble
is crowned by a small roof and rooster that crows at the end of the
show. Architecturally, it transforms the tower’s plain southern face
into Prague’s most theatrical civic facade.
Facades and
Decorative Details
Southern facade: Late-Gothic portal (end 15th
century) with ogee arch, finial, and richly carved archivolts;
Renaissance three-light window (post-1526) inscribed “Praga caput regni”
with pilasters, tympanum bearing Prague’s coat of arms, and Gothic
canopies on side windows; Neo-Gothic gables and oriel on the Cockerel
House.
Western facade: Original Gothic portal with mouldings;
Neo-Renaissance elements on Mikeš House (high windows, inscription
“Dignitatis memores — ad optima intenti”).
Minute House facade:
17th-century sgraffito (classical and biblical scenes, revealed 1905).
Materials throughout: local sandstone and limestone for load-bearing
walls and carvings, terra-cotta roof tiles, polished red marble for
Renaissance portals, wood for panelling and ceilings, and later mosaics.
Interiors — Gothic Core with Later Layers
The interiors preserve
the most atmospheric late-Gothic spaces in Prague:
Entrance halls:
Late-Gothic net vault (end 15th century); 1930s mosaics by Vojtěch Ignác
Ullmann after Mikoláš Aleš depicting Libuše’s prophecy and Slav homage
to Prague.
Council Chamber (c. 1470): Late-Gothic net vault on two
pillars; polychrome coffered wooden ceiling (second half 16th century)
with gilded chains (1638); Gothic wooden panelling with 46 guild and
town coats of arms; Ecce Homo sculpture (Bohemian High Gothic, c. 1410)
on a carved bracket with angel and the inscription “Juste iudicate filii
hominis”; Baroque tiled stove (1736).
Jiřík Hall and Brožík Hall:
15th-century wall paintings, 19th-century historical canvases by Václav
Brožík, and 1930s modifications by Pavel Janák.
Underground:
Romanesque-Gothic cellars with ribbed vaults, passageways, and prison
cells from the original 13th–14th-century houses — a rare preserved
medieval merchant-house layout.
The 1945 fire destroyed the large
public hall and damaged the chapel and clock, but sensitive post-war
restoration (architects J. Koreček, J. O. Lankáš, and others) respected
the historic fabric while adding modern access (elevators, 2000 and 1927
original preserved elsewhere).
