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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
