Aizupe Manor (Latvian: Aizupes muižas pils) was built in late classicism style in 1823. In 1561 the estate was the property of the Duke, who granted the manor to his counselor Salamon Henning. In 1719, the manor became property of his heirs, and later von Koskulu's, and von Mirbahu's. From 1793 to 1920, the manor was in the hands of the Hahn family.
The manor then remained a 19th century farm complex with residential houses, large barns with ramps, distillery, and a park established between 1830-1840 next to the manor house until the beginning of the 20th century. From 1939 to 1945, it was occupied by the Cīrava Forest School, and from the 1945 to 1985 by the Forest Technical School. Since the 1990s it has been under control of the Cīrava municipal council.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.
