The medieval stone church of Ambla is the oldest in Central Estonia. Construction of the church was started in the mid-13th century. The church has been consecrated in the name of Virgin Mary, the main patron saint of Teutonic Order. In Latin the church is called Ampla Maria (Mary the Majestic), which also has given the name for the village.
The Renaissance-style interior was mainly destroyed in Livonian Wars, but there still exist an altarpiece and pulpit made in 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.
