Old town hall in Prostějov, Renaissance town hall and museum in Prostějov, Czech Republic

The Old Town Hall consists of two originally separate houses on the square near the Church of the Exaltation of the Holy Cross. Its main three-storey facade faces the square, fronted by a roofed arcade loggia with nine arches that extends one bay beyond the building on each side. A stone staircase on the west leads to the main entrance in the loggia, framed by a Renaissance portal with reliefs of town privileges and the names of mayors, lions on the base and the town coat of arms in the pediment.

The town hall was decided on in 1521, when Prostějov bought two burgher houses on the square near the Church of the Exaltation of the Holy Cross. An unknown architect designed a 21-metre-long, single-storey building pushed forward into the square; it was finished in 1530, and a Renaissance portal followed in 1538-1539. A fire in 1697 destroyed the roof and first-floor rooms, and the Baroque rebuilding, probably by Giovanni Pietro Tencalla, was completed in 1698.

The building has housed the Museum and Gallery of the City of Prostějov since 1905, when the Ethnographic and Industrial Museum of Prostějov and Haná moved in. Its name refers to the town hall that served the town from 1530 until the district court occupied it in 1848–1903. Look for the three coats of arms with dates on the studded door at the southeast corner: Schellenberg 1390, Pernštejn 1490 and Liechtenstein 1599.

The museum entrance is on the first floor, reached by a stone staircase on the western side of the arcaded loggia. The loggia itself is open from the square and its nine arches can be viewed at any time. The side wing, connected by a passage through an open bay on the second floor, holds the museum's service rooms.

The arcaded loggia in front of the main facade is one bay wider than the building on each side. The second floor is a blind attic with swallowtail crenellation. On the southeast corner, studded doors bear three coats of arms with the dates 1390, 1490 and 1599, tied to events in the town's history.
