Riga Old Town (Vecrīga) is the historical center of Riga, Latvia, located on the east side of Daugava River. Vecrīga is famous for its old churches and cathedrals, such as Riga Cathedral and St. Peter's church.
Vecrīga is the original area of Riga and consists of the historic city limits before the city was greatly expanded over the years. In the old days, Vecrīga was protected by a surrounding wall except the side adjacent to the Daugava river bank. When the wall was torn down, the waters from Daugava filled the space creating Riga City Canal.
In the 1980s Vecrīga's streets were closed to traffic and only area residents and local delivery vehicles are allowed within Vecrīga's limits with special permits. Vecrīga is part of a UNESCO World Heritage Site listed as "Historic Centre of Riga".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.
