Town hall in Jilemnice, Town hall in Jilemnice, Czech Republic

The Town hall in Jilemnice is a classicist building at the southern end of the western front of Masaryk Square, with a thirty-metre prismatic tower topped by a tent roof and a nearly three-metre lantern above the corner of Jana Harracha Street. Its stone basement with supporting vaults dates from the 17th century, and a five-axis arcade runs along the ground floor.

The town hall likely stands on the site of a medieval reeve's house; a wooden building is first mentioned in connection with the town fire of 1634 and was rebuilt after the fire of 1646. After the fire of 1781 a new building with a five-axis arcade and a tall gable roof rose on the surviving 17th-century vaulted stone basement. In 1851–54 it was extended southward by two vaulted bays and a 30-metre square masonry tower with a tent roof and lantern was added at the corner, fitted with wooden dials almost two metres across.

The tower clock, made by local master Josef Pochop in 1842 and given a repeating mechanism in 1854 on the initiative of mayor Dominik Jerie, strikes every quarter hour. A small bell counts the quarters, a middle bell the hours, and at each full hour a large bell repeats the hour count, giving 1,020 strikes a day. Locals call it the hardest-working clock in Europe.

The building sits centrally on the main plaza and is easily reached by following the streets that lead to it. The immediate surroundings are walkable and connect naturally to other important town locations.

The tower is a square, thirty-metre-high prism with a tent roof and a lantern nearly three metres tall, not an octagonal design. Its nearly two-metre wooden dials on all walls are driven by a clockwork moved from the old turret. The clock strikes 1,020 times a day, earning it the name "the hardest-working clock in Europe".
