The walls which enclose the town of Moniga del Garda were built in the 10th century to face the Hungarian invasions. The castle was founded in the same period and is still in fairly good condition. Rectangular in shape (60 × 80), there is only one entrance at the centre of the eastern wall, where signs of an old drawbridge can still be seen. The crenulated city walls have four small round lookout towers on each corner. Three more towers are situated at the centre of the north, south and west walls. The square keep is now a bell tower.
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.
