Venø Church's age is difficult to date but it was probably built around the time of the Reformation (1536), making it the oldest building on the island. According to tradition, it is the smallest church in Denmark measuring only 9.8 by 4.2 meters. The low ceiling and the limited seating capacity (only about 50 places) reinforce this impression. The church is built of fieldstone while brick has been used for the corners and later extensions. There is no tower as the church bell is inside the gable at the west end of the church.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.
