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:Duino Castle was built by the Wallsee family in 1389 on the cliffs overlooking the Gulf of Trieste. It replaced an older castle from the 11th century. Over time, the Wallsee family disappeared and the castle, after having been used as a prison, became the residence of the Luogar and Hofer.
At the end of the 19th century it became the property of Prince Alexander von Thurn und Taxis from the Czech branch of the House of Thurn and Taxis. It remains with the family to this day with his great-grandson Prince Carlo Alessandro della Torre e Tasso, Duke of Castel Duino the current owner. The castle has been opened to the public as a museum and park.
