The Château de Castelnau-de-Lévis was built at the beginning of the 13th century by Gicard Alamon, and called Castelnau de Bonnafonds. It was rebuilt by the Lévis in the 15th century, when the seigneurie came into the possession of Hugues d' Amboise, baron d'Aubijoux; the fief remained with his descendants until the seventeenth century. Hugues' grandson, Louis d'Amboise, comte d'Aubijoux and baron de Castelnau-de Bonnafous, restored the castle and dwelt in it. The narrow square watchtower (tour de guet) is 40m tall.
Apart from the watchtower, all that remains today are remnants of other buildings. From the castle, there is a good view of Albi and the Tarn valley.
The castle is privately owned.
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.
