Cordouan lighthouse is located 7 kilometres at sea, near the mouth of the Gironde estuary in France. At a height of 67.5 metres, it is the tenth-tallest 'traditional lighthouse' in the world.
The Tour de Cordouan, the 'Patriarch of Lighthouses', is by far the oldest lighthouse in France. It was designed by leading Paris architect Louis de Foix, and is something of a Renaissance masterpiece, an amalgam of royal palace, cathedral and fort. Started in 1584 and finished in 1611, it still stands today. Three stories were added in the 18th century.
It was listed as a historic monument in 1862, and recognized by UNESCO as a World Heritage Site in 2021.
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.
