Peschiera del Garda was once the site of an ancient lake-dwelling settlement. The fortress played a prominent part in most military campaigns conducted in northern Italy after 1400. In the middle of the 16th century the fortress and town passed into the hands of the Venetians, who ordered reconstruction of the fortress according to projects by Guidobaldo da Urbino and Sanmicheli. Napoleon added two new fortresses there. At the beginning of the 19th century the Austrians redesigned and expanded the fort. With Mantua, Verona, and Legnano, it became one of the strongholds of the Quadruple Alliance. After the end of the Third War of Independence (1866), Peschiera del Garda became part of the Kingdom of Italy. During the First Italian War of Independence, it was taken by the Piedmontese from the Austrians, after a gallant defence by General Rath lasting six weeks, on May 30, 1848.References:
The city walls of Avila were built in the 11th century to protect the citizens from the Moors. They have been well maintained throughout the centuries and are now a major tourist attraction as well as a UNESCO World Heritage Site. Visitors can walk around about half of the length of the walls.
The layout of the city is an even quadrilateral with a perimeter of 2,516 m. Its walls, which consist in part of stones already used in earlier constructions, have an average thickness of 3 m. Access to the city is afforded by nine gates of different periods; twin 20 m high towers, linked by a semi-circular arch, flank the oldest ones, Puerta de San Vicente and Puerta del Alcázar.
