Poznań Town Hall is a historic city hall in the city of Poznań, Poland, located at the Poznań Old Town in the centre of Old Market Square. It used to serve as the Seat of local government until 1939, and now houses a museum. The town hall was originally built in the late 13th century following the founding of the medieval city in 1253; it was rebuilt in roughly its present-day form, in mannerist style, with an ornate loggia, by Giovanni Battista di Quadro in 1550–1560. The display of mechanical fighting goats, played out daily at noon above the clock on the front wall of the building, is one of the city's main tourist attractions.
