Porta Siberia is a massive gate, dating back to 1551-53. It was the work of Galeazzo Alessi and once formed part of the 16th-century walls. Its name derives from 'cibaria' (foodstuffs), for it was through this gate that the city's produce passed, both on arrival from the sea and departure towards other ports in the Mediterranean.Once used as a customs area, after the Old Port was restructured it was turned into a museum devoted to the painter and set designer Emanuele Luzzati, housing temporary exhibitions by the Genoese artist and by leading contemporary illustrators.
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.
