Alberga Manor was first mentioned in the 1620s. The current main building was built as a summer residence by council Feodor Kiseleff in 1874–1876. Later it was in the possession of Helsinki city and left to decay. The main restoration was made in 1997 and today Alberga is used by Espoo City culture office.
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.
