Heers Castle built in the 13th century. Of its many owners, among the most notorious was Raes van Heers (1418–77), who was defeated and driven into exile by Charles the Bold at the Battle of Brustem in 1467. The castle, and the town of Heers, were laid waste by Charles's troops, although the castle was eventually repaired after Raes' death by his widow.
The family de Rivière d'Arschot lived here until the 18th century, when Barbara, daughter and heiress of the last Count, Henri de Rivière d'Arschot, became abbess of Herkenrode Abbey; on her death in 1744, the family became extinct.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.
