Arch of Trajan in Mérida was an entrance arch, possibly to the provincial forum. It was located in the Cardo Maximus, one of the main streets of the city and connected it to the municipal forum. Made of granite and originally faced with marble, it measures 14 metres high, 5.7 metres wide and 8.7 metres internal diameter. It is believed to have a triumphal character, although it could also serve as a prelude to the Provincial Forum. Its name is arbitrary, as the commemorative inscription was lost centuries ago.
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.
