Carriages await the visitors on the main square in the castle district, around the Trinity column built to commemorate the plague epidemics in the 17th and 18th century. Admire the beautiful Mathias church and in one of the corners, the Baroque palace (built at the end of the 17th century), which housed Buda's former town hall. A pinnacle turret with a clock rises above what was formerly a chapel. The statue of Athena, the town's guardian, is set in a niche.
