The remains of the Stegeborg castle are situated beautifully on a little island in the sea channel leading toward Söderköping. In the Middle Ages the castle was one of the most important strongholds in Sweden and also a royal palace. The oldest parts of the castle is a brick tower in the southeast corner, built in the early 13th century.
In the 18th century the castle was in bad shape and some wooden buildings were even were auctioned off. In 1938 the Swedish National Heritage Board received a small sum to clear the location of trees and repair the worst damage and raise protective roofing over certain parts. The new main building (a private residence) was completed in 1806. The herb-garden was laid out in 1988 by the present owner.
Today Stegeborg is open for tourists and the castle ruins are now also a port tavern and a marina.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.
