The Old church of Saint Bartholomew is a fortified church in Gliwice. Originally, it was built in Romanesque style about 1232 and situated far outside the defensive walls of the city.
In the 15th century, it was enlarged in Gothic style. The western tower was enhanced using brick. Its character is rather military, than that of a steeple.
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.
