The Abbey of St. Vaast was founded in 667. Saint Vedast, or Vaast (c. 453–540) was the first bishop of Arras and later also bishop of Cambrai, and was buried in the old cathedral at Arras. In 667 Saint Auburt, seventh bishop of Arras, began to build an abbey for Benedictine monks on the site of a little chapel which Saint Vedast had erected in honour of Saint Peter. Vedast's relics were transferred to the new abbey, which was completed by Auburt's successor and generously endowed by King Theuderic III, who together with his wife was afterwards buried there.
The Abbey of St. Vaast was of great importance amongst the monasteries of the Low Countries. It was exempt from episcopal jurisdiction and maintained its independence until 1778, when it was aggregated to the Congregation of Cluny.
At the French Revolution it was suppressed and the monastic buildings were used first as a hospital and then as barracks. In 1838 the premises were purchased by the town; part was used as a museum and archive, and the rest as the residence of the bishop. The abbey church, which had been desecrated and partially destroyed, was rebuilt and consecrated in 1833 and now serves as the cathedral of Arras, substituting for the former Gothic cathedral destroyed during the Revolution. The abbey houses the Musée des beaux-arts d'Arras.
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.
