Las Bóvedas (the domes) is the local name for the remains of some Roman baths near San Pedro de Alcántara in Andalusia, near Marbella. They are located close to the Paleo-Christian Basilica, Vega del Mar. Historians are still unsure of the baths' true origins, though most believe that they are all that remain of the Roman settlement known as Cilniana (or Silniana) destroyed by an earthquake in 365 AD. They can be visited along with the better conserved Villa Romana (Roman villa).
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.
