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:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
