The current building of Pöide Church is believed to be built on the remains of a chapel built in 13th century. After the conquest of Saaremaa in 1227, the eastern part of Saaremaa belonged to the Livonian Order, who built a fortress at Pöide as their headquarters during the second half of the 13th century. This fortress was destroyed by the Saaremaa natives during the wave of uprisings against the occupying forces that took place in Estonia and Saaremaa during St.George's Night Uprising of 1343. There was a chapel on the southern side of the fortress, and the walls of this chapel form the central part of Pöide church. For its massive form, it is called fortress-church.
The building was looted and burnt during World War II and also used as a storage building. The building suffered severe damages in fire in 1940, when lightning struck the tower. The large crack in the tower from the lightning can still be seen today.Pöide church has been renovated and reconstructed slowly since 1989. Choir-part, stone-altar and vestry room have been renovated. Several big tombstones inside the church are exposed behind glass, showing the importance of the church as a cultural center for nearby communities during previous centuries.

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.
