Helsinki Cathedral is a distinct landmark in the scenery of central Helsinki, with a tall green dome surrounded by four smaller domes. It was built in 1830–1852 in neoclassical style to replace an earlier church from 1727. The cathedral was designed by Carl Ludvig Engel, to form the climax of the whole Senate Square laid out by Engel, surrounded by a number of buildings all designed by him.
Today the cathedral is one of the most popular tourist attractions in Helsinki. Annually more than 350,000 people visit the church, some of them to attend religious events, but most as tourists. The church is in regular use for both worship services and special events such as weddings.
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.
