Koeru Church is one of the oldest medieval churches in Järvamaa with a beautiful Baroque tower. The church was built probably in the mid-13th century and expanded to the three-nave form aroud 1300.
The church was damaged badly in Livonian Wars and again in Great Northern War. It was mainly reconstructed in 1721. The present 43m high tower was built in the end of 18th century. The pulpit, altarpiece and crucifix in the church date from the 17th century.
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.
