St. John the Baptist Church is considered to be the acme of the Yaroslavl school of architecture. It was built in 1671-1687 on the bank of Kotorosl river. Its walls and dome drums are covered with richly glazed tiles; the temple's fifteen onion domes are assembled in three groups. The 7-storey, 45-metre high bell-tower was built later than the church itself in mid-1690s. The entire interior is covered with frescoes depicting Christian saints, St. John the Baptist hagiography and biblical topics. They were painted by Dmitry Plekhanov and Fyodor Ignatyev in 1694-1695.
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.
