Källunge church (Källunge kyrka) is a church in the island-bishopric of Visby on Gotland. The church is richly decorated with reliefs and frescoes. The frescoes are important evidence of the strong Byzantine influence on Swedish art of the 12th and 13th centuries. An early depiction of a nyckelharpa is found in a relief dating from circa 1350 on one of the gates of the church.
The church gives its name to the Källunge codex (Latin Codex Kellungensis) a 1622 collection of choral music by Philipp Dulichius, Melchior Vulpius, Gregor Aichinger, Nicolaus Zangius,Hieronymus Praetorius, Hans Hassler, Jacobus Gallus, Johann Walter, Dominique Phinot, Orlando di Lasso, and Johann Bahr among others. The collection was discovered in 1913, though only the alto part is extant. 100 of the 315 pieces have been identified from other collections.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.
