Courthouse in Bytom, Renaissance Revival courthouse in Śródmieście, Bytom, Poland.

The Courthouse in Bytom is a T-shaped, three-storey brick building with a usable attic, basement and loft, covering 2,568.2 m² with 3,156 m² of usable floor area. Its front façade has a central bay with a rounded gable, and window and door surrounds are made of pink sandstone. The east wing, added in 1891–1895, contains a three-storey arcaded courtyard with cloisters, heraldic cartouches on pilasters and a large clock at the fork of the enfilade staircase.

The original brick courthouse was built in 1860 to a design by Paul Jackisch, together with the adjoining prison complex at the western edge of Bytom. In 1891–1895 an eastern wing in North Neo-Renaissance style was added for the district and regional courts, at a cost of 684,000 marks. From 1916 the building housed criminal chambers, while civil cases moved to Parkowa Street.

The courthouse received recognition as an immovable monument under registration number A/579/2019, marking its importance in Polish architectural heritage.

The building stands at the western edge of Bytom's old town, next to the prison complex, with two annexes at Wrocławska 2 housing a florist and an insurance office. The courthouse is an active court, so interior access is limited to public areas during hearings; the arcaded courtyard and three historic courtrooms are not open to tourists. The 2007 renovation repaired mining damage, including a 50 cm vertical tilt between the north and south sides.

The eastern wing's three-storey arcaded courtyard has a glazed roof, and its pilasters carry cartouches with the arms of Bytom and the district plus a pair of scales. A large clock sits where the enfilade staircase forks. The granite mosaic floor survives, as do three ceremonial courtrooms with original fittings.
