Korskirken is located at the intersection of the streets Kong Oscars gate and Nedre Korskirkeallmenning and dates back to the latter half of the 12th century. The name of the church refers to the True Cross (and not to its cruciform plan), and is usually rendered in English as 'Holy Cross Church'. This is because it was, as one of only a Norwegian churches, in possession of a relic from the True Cross. This relic was later stolen by the Danish king, along with several other relics from all over the country, during the Reformation.
Korskirken was first mentioned in Sverris saga from 1185. At the time of construction, the church was situated on the shore of Vågen, probably marking the southern border of settlement in Bergen. Korskirken was damaged in the fires of 1198, 1248, 1413, 1582, 1623, 1640 and 1702; the church originally had two towers, but one was destroyed in the 1582 fire and never rebuilt. It was originally built with straight rectangular plan. The church got its cruciform plan when transepts were added around 1615-1623.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.
