The Church of the Holy Trinity (Heliga Trefaldighets Kyrka) was built in the 13th century; the earliest plans were of a monastery for an order of Franciscan monks which had settled in Arboga. Early in the 16th century Gustav Vasa started Reformation in Sweden and the monastery was opened as a church for the people of Arboga.
During renovations in the 17th century a church tower was added to the building. Among the artifacts of the church is the pulpit from 1736, beautifully carved by the royal sculptor Buchard Precht. The light fittings in brass are believed to be the largest in Sweden, possibly the whole of Scandinavia. 13th century murals are displayed on the south wall, including a depiction of the life of Saint Francis.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.
