Gjellerup Church, built in the 12th century, is unique for its Latin inscription in the tympanon above former door facing to the south. The inscription, carved in 1140, makes Gjellerup Church the oldest dated building in Denmark. The church is consecrated to the Roman martyr St. Laurentius. There are traces of a Romanesque tower, and the sheer size of the church is remarkable. The oldest parts are the chancel and nave. The southern nave was added around 1540, the porch oin 1650 and current tower in 1784.
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.
