Medininkai Castle was built in the late 13th century or the first quarter of the 14th century. The defensive perimeter of the castle was 6.5 hectares; it is the largest enclosure type castle in Lithuania.
The castle was built on plain ground and was designed for flank defence. The rectangular castle's yard covered approximately 1.8 hectares and was protected by walls 15 metres high and 2 metres thick. The castle had 4 gates and towers. The main tower (donjon), about 30 metres high, was used for residential quarters. Medininkai was first mentioned in 1392. The castle was badly damaged by a major fire in the late 15th century. Because of increased use of firearms, this type of castle was no longer suited for defensive purposes and was later used as a residence. In 1655 during the war with Russia the castle was badly damaged and never reconstructed again. During the Second World War Germans set their gun arsenal in one of towers of Medininkai castle. The tower was burst when Germans retreated. The castle was not repaired until 1960. Only then slow reconstruction works were started, however, full reconstruction was not finished until now.
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.
