Opheylissem Castle is a large stately home in Hélécine, Belgium. The present building represents the remains of the former Premonstratensian Opheylissem Abbey, which was dissolved in 1796. Most of the buildings were destroyed, but the abbot's house (prelatuur) remained, and in 1870 was restructured by the architect Alphonse Balat in its present form. Balat laid out the surrounding park at the same time.
The house and park were acquired by the Province of Brabant, and after 1995 became that of the Province of Walloon Brabant.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.
