The Communal Palace is situated at the northern end of the main square of the old part of the City of Pula, called the Forum Square. The spot occupied by the Palace has been used for the public buildings since Ancient Rome, when the place was used as a part of a triade of Roman temples, of which today only the Temple of Augustus remains. The eastern of these temples, called the Temple of Diana, was used as a rudimentary city hall from the 9th century.
As the city prospered, there was a need to construct a dedicated place which would serve as a city hall, so the construction of the new city hall at the site of the Temple of Diana began near the end of the 13th century, and the new city hall was finished in 1296.
The building was constructed in Gothic style using the material of the old Roman temples and other building on the site, retaining their walls when possible. Even today, the whole northern part of the Temple of Diana is clearly visible at the back side of the Communal Palace.
Since the construction, the Communal Palace has seen numerous reconstructions. At the end of the 15th century the building was reconstructed in Renaissance style and during the 17th century, the building was again reconstructed, now in Baroque style.
The present state of building is due to several reconstructions made during the 19th and 20th centuries, the last of which was finished in 1988.References:
Sirmione castle was built near the end of the 12th century as part of a defensive network surrounding Verona. The castle was maintained and extended first as part of the Veronese protection against their rivals in Milan and later under the control of the Venetian inland empire. The massive fortress is totally surrounded by water and has an inner porch which houses a Roman and Medieval lapidary. From the drawbridge, a staircase leads to the walkways above the walls, providing a marvellous view of the harbour that once sheltered the Scaliger fleet. The doors were fitted with a variety of locking systems, including a drawbridge for horses, carriages and pedestrians, a metal grate and, more recently, double hinged doors. Venice conquered Sirmione in 1405, immediately adopting provisions to render the fortress even more secure, fortifying its outer walls and widening the harbour.
Thanks to its strategical geographical location as a border outpost, Sirmione became a crucial defence and control garrison for the ruling nobles, retaining this function until the 16th century, when its role was taken up by Peschiera del Garda.
