Simiane-la-Rotonde has remained practically unchanged for centuries. On the hilltop stands the truncated cone-shaped edifice that gave Simiane-la-Rotonde its name: the keep, or rotunda, of the old Château des Simiane-Agoult. Built in the 12th century, its massive exterior is remarkable for its hexagonal shape. The interior, an uneven dodecagon, is especially splendid. It is a vast room with a series of arches topped by finely sculpted capitals. The ceiling has a stone cupola of 12 ribbed vaults towering five metres high. It is an amazing example of Romanesque architecture, both civil and military.
The southern wing of the castle has also been restored and you can visit parts of the main building and the fortifications. The rooms on the ground floor date from the Middle Ages and recount the castle's history. The upper floor, in Renaissance style, houses the Sainte Victoire Aromatherapy Laboratory, which offers workshops in essential oils to the public.The castle is also the magical setting for exhibitions and the international festival of early music Les Riches Heures Musicales de la Rotonde in August.
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.
