The Roman bridge in Sommières is 190m long. It was built on the instructions of Emperor Tiberius at the start of the 1st century. It was restored in the 18th century. At the town end of the bridge is the gothic town gate known as the 'Tour de l'Horloge'. Only 7 of the 19 arches can be seen, the others lie beneath the town where they act as cellars.
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.
