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:The Walls of Constantinople are a series of defensive stone walls that have surrounded and protected the city of Constantinople (today Istanbul) since its founding as the new capital of the Roman Empire by Constantine the Great. With numerous additions and modifications during their history, they were the last great fortification system of antiquity, and one of the most complex and elaborate systems ever built. They were also the largest and strongest fortification in both the ancient and medieval world.
Initially built by Constantine the Great, the walls surrounded the new city on all sides, protecting it against attack from both sea and land. As the city grew, the famous double line of the Theodosian Walls was built in the 5th century. Although the other sections of the walls were less elaborate, they were, when well-manned, almost impregnable for any medieval besieger.
