The Church of the Holy Archangels Michael and Gabriel in Nesebar, Bulgaria, is a partially preserved medieval Eastern Orthodox church, built in the 13th or 14th century. As part of the Ancient Nesebar UNESCO World Heritage Site, it stands in the old town and has been under state protection since 1927. The church, with a cross-in-square plan, features three apses and a large narthex. Despite partial preservation, it remains culturally significant, boasting opulent external decoration characteristic of Nesebar's medieval religious architecture. The architectural style, opus mixtum, incorporates alternating rows of brickwork and stones in a chequered pattern.
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.
