In 1589, Maréchal de Villars supervised the construction of a small fort on the hill known as 'colline des Moulins' overlooking Saint-Tropez. This fort was destroyed in 1595, but the military engineer Raymond de Bonnefons chose the same site to build further defensive structures from the start of the 17th century.
The hexagonal tower, which formed an essential part of the village's defence system, was erected between 1602 and 1607. The Citadel underwent numerous modifications over the centuries, before falling into disuse in the 19th century, when the strategic interest of this perfectly-preserved fortress finally diminished.
The old cannons are still in place facing out towards to sea, and the views from the top are stunning across the Gulf and the Mediterranean Sea.
Bought up by the town in 1993 and made a listed monument, today it hosts a museum dedicated to the history of Saint Tropez and its relationship with the sea.
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.
