The Vietnam Veterans Memorial is a 2-acre (8,000 m²) national memorial in Washington, DC. It honors U.S. service members of the U.S. armed forces who fought in the Vietnam War, service members who died in service in Vietnam/South East Asia, and those service members who were unaccounted for during the War.
Its construction and related issues have been the source of controversies, some of which have resulted in additions to the memorial complex. The memorial currently consists of three separate parts: the Three Servicemen Memorial, the Vietnam Women's Memorial, and the Vietnam Veterans Memorial Wall, which is the best-known part of the memorial.
The main part of the memorial was completed in 1982. The memorial is maintained by the U.S. National Park Service, and receives around 3 million visitors each year.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.
