Gudsberga Abbey (Gudsberga Kloster) was a Cistercian abbey established in 1486. It was the last Cistercian abbey in Sweden. Gudsberga owned farms, manors, foundries and mines until 1527, when it was reduced to the Crown during Reformation. In 1538 and 1544 King Gustav Vasa ordered to send silver from abbey to Stockholm. It was demolished later. Today some stone foundations remain and there is a museum exhibiting the forge of abbey.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.
