Church of Santa María a Real do Sar was built in the 12th century on the outskirts of the city. Interesting elements on the exterior are the small tower on the façade and the sturdy flying buttresses built between the 17th and 18th centuries. It has a basilical floor plan with three naves, separated by composite pillars decorated with plant motifs. It is covered with barrel vaults reinforced by rib arches. The sanctuary of the collegiate church has three apses; the central one is polygonal and the two side ones are semicircular. The interior lighting comes from the side openings and the rose window on the façade. Elements worth noting in the cloister include the decoration on the capitals, made by the workshop of Master Mateo.
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.
