Vác's renovated main square has the town's most colourful buildings, including the Town Hall (1764), considered a baroque masterpiece. Note the statue of Justice and the seals held by the two figures on the gable – they represent Hungary and Bishop Kristóf Migazzi, the driving force behind Vác’s reconstruction more than two centuries ago. In the square's centre, you'll see the entrance to a crypt , the only remnant of the medieval Church of St Michael. Tourinform holds the key.
