The Church of San Pedro Apóstol is considered a National Historic-Artistic Monument in Vitoria from the 13th-14th centuries. The temple was attached to the western wall of the medieval town, which is why the walls on the west are very thick. In the central nave the walls form a tower which is visible from the outside of the temple.
Gothic façade dates from the 14th century, accessible from Calle Herrería. The entrance is the opposite way round in this church because the wall used to run along the bottom of the central nave.
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.
