The Monastery of Dumio (São Martinho de Dume), is a former paleo-Christian monastery in the civil parish of Dume, municipality of Braga, in northwestern Portugal. Originally a Roman villa, it was the base of a basilica by Suebi tribes, and later Christian monastery headed by Martin of Braga in the 6th century (c. 550–560). The re-discovery of the Roman ruins in the late 20th century resulted in archaeological excavations that unearthed its former use.
The ruins are located around the Lugar da Igreja or Lugar do Assento on the square occupied by the parochial church of Dume. Occupying a rural landscape, the space is an ample property that include the Church of São Martinho de Dume, constituted by a central nucleus of the courtyard, the chapel of Nossa Senhora do Rosário and backyard of the Casa do Assento, on the same block occupied by the local cemetery.
The archaeological ruins in Dume encompass a complex of structures that include: a grande Roman villa (with a habitational zone) and bathhouse; remnants of a granite basilica in the form of a Latin cross (oriented east to west); with regularly horizontal aligned deposits in mortar, pavement and polychromatic mosaics; and a necropolis consisting of twelve graves, located in an area defined by granite slabs and/or brick coverage. These individual spaces were occupied successively over a 2000-year period.
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.
