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:House of the Blackheads (Melngalvju nams) is a building situated in the old town of Riga. The original building was erected during the first third of the 14th century for the Brotherhood of Blackheads, a guild for unmarried German merchants in Riga. Major works were done in the years 1580 and 1886, adding most of the ornaments.
The structure was bombed to a ruin by the Germans June 28, 1941 and the remains demolished by the Soviets in 1948. The current reconstruction was erected from 1995 to 1999. Today the House of Blackheads serves as a museum and sometimes concert hall.
