The fine Gotlands Fornsal Museum provides comprehensive coverage of Visby's past. Housed in an 18th century distillery and a medieval warehouse, it holds five storeys of exhibition halls covering eight thousand years of history, as well as a good courtyard café and bookshop.
Among the most impressive sections are the Hall of Picture Stones, a collection of richly carved stones dating mostly from the 5th to 11th centuries, and the display of the Spillings Hoard – the richest of Gotland's seven hundred hoards. Found in 1999, this treasure, mostly from the Arab world, England and Germany, weighs 85 kilos. The Hall of Prehistoric Graves is equally fascinating, its glass cases displaying skeletons dating back six thousand years.
Other rooms trace the history of medieval Visby, with exhibits including a trading booth, where the burghers of Visby and foreign merchants dealt in commodities – furs, lime, wax, honey and tar – brought from all over Northern Europe. A series of tableaux brings the exhibition up to 1900, starting with Erik of Pomerania, the first resident of Visborg Castle, and leading on through the years of Danish rule, up to the island's 16th-century trading boom.
References:Château de Niort is a medieval castle in the French town of Niort. It consists of two square towers, linked by a 15th-century building and dominates the Sèvre Niortaise valley.
The two donjons are the only remaining part of the castle. The castle was started by Henry II Plantagenet in the 12th century and completed by Richard the Lionheart. It was defended by a rectangular curtain wall and was damaged during the Wars of Religion. In the 18th century, the castle served as a prison.
The present keeps were the central point of a massive fortress. The southern keep is 28m tall, reinforced with turrets. The northern tower is slightly shorter at 23m. Both are flanked with circular turrets at the corners as well as semicircular buttresses. Each of the towers has a spiral staircase serving the upper floors. The Romanesque architecture is of a high quality with the dressed stones closely jointed.
