The Church of Christ Pantocrator is a medieval Eastern Orthodox church in Nesebar, on the Black Sea coast. It is usually dated to the late 13th or early 14th century. The church, today an art gallery, survives largely intact and is among Bulgaria's best preserved churches of the Middle Ages.
The best-known feature of the Church of Christ Pantocrator is the rich and colourful decoration of its exterior walls. The most lavishly decorated part of the church is the east side with the apse, and as a whole all sides of the church exhibit different ornamentation. Interchanging strips of three or four rows of bricks and carved stones, which create an optical pattern, are the most basic type of decoration used.
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.
