The buildings of former Daoulas Abbey - a cloister and a 12th century font, an oratory and a monumental 16th century fountain, together with the 18th century conventual house - are an exceptional tribute to Breton art from the 10th century onwards. It was established by Guyomarch IV de Léon in 1173, but there has been at least a church since the 6th century. The former abbey was raided and looted by Vikings.
Daoulas Abbey was secularized in 1771-1792 and moved as a private property. The abbey has been renowned since 1986 for the quality and originality of its archaeological, historical or ethnological exhibitions organised in collaboration with some of the most known world wide museums. The abbey houses a superb medicinal garden with over 250 species. It is still structured and organised like most middle age/renaissance convent or monastery gardens.
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.
