In 72 BCE the Roman General Pompey, while on the way back to Rome after a military campaign in Spain, founded a Roman colony in Saint-Bertrand-de-Comminges. The goal was to defend the passage to the Aran Valley and the Iberian peninsula. The colony was named Lugdunum Convenarum and had reached around 30,000 people at its highest point. It belonged to the Roman province of Novempopulana and had a growing Christian community, which by the late fourth century got its own Diocese of Comminges, which was suffragan of the Metropolitan Archdiocese of Eauze.
It is believed to have been the place of exile from 39 AD of Herod Antipas, with his wife Herodias, under Emperor Caligula's orders. In 405 the Vandals sacked the city and forced the peasantry to move to the citadel.
In an open field just outside the village centre, this small archaeological site has a few ruins from the town's Roman days. You'll have to use your imagination to picture the theatre, market, temple and other public buildings from the fragments of low-rising stone foundations.
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.
