The square on the island summit is the central location of the town and its layout was already defined in the 13th century. Its east boundary was demarcated by the town tower and the Romanesque cathedral. The square ended in two palaces and the town loggia on the south, whilst the north and the west sides were formed by two smaller palaces. The 15th century was a time of great building activity in the town and the most important buildings on the Town Square are from that period. The Praetorial Palace was built in 1447 - 1481, Foresteria (lodgings) in 1458-1460, the cathedral with its façade facing the square underwent alterations from the mid-15th to the end of the 16th century, whilst the town tower was reconstructed in 1418-1480. The Loggia was built in 1462-1464 and Platea Communis was paved in 1505. Representative buildings in the square have, despite later alterations and additions, retained their air of the Venetian Gothic period to the present day. In the middle of the square, which still exhibits the characteristics of the medieval Mediterranean area, one must also picture the pedestal for the town banner. The restoration of the square, one of the most beautiful areas of the entire territory of the former Venetian Republic, and its revitalisation have been on going since 1964. Especially meaningful was the moving of the town hall into the Praetorial Palace.
