Mantua Cathedral (Duomo di Mantova) is the seat of the Bishop of Mantua. An initial structure probably existed on the site in the Early Christian era, which was followed by a building destroyed by a fire in 894. The current church was rebuilt in 1395–1401 with the addition of side chapels and a Gothic west front, which can still be seen in a sketch by Domenico Morone (preserved in the Palazzo Ducale of Mantua). The bell tower has seven bells.
After another fire in the 16th century, Giulio Romano rebuilt the interior but saved the frontage, which was replaced however in 1756–61 by the current Baroque one in Carrara marble. Notable characteristics of the Renaissance structure are the cusps, decorated with rose windows on the south side, which end at the Gothic bell tower.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.
