The Groeningemuseum is built on the site of the medieval Eekhout Abbey. It houses a comprehensive survey of six centuries of Flemish and Belgian painting, from Jan van Eyck to Marcel Broodthaers. The museum's many highlights include its collection of 'Flemish Primitive' art, works by a wide range of Renaissance and Baroque masters, as well as a selection of paintings from the 18th and 19th century neo-classical and realist periods, milestones of Belgian symbolism and modernism, masterpieces of Flemish expressionism and many items from the city's collection of post-war modern art.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.
