Ennsegg castle was built originally around the year 900. In the end of the 15th century it was so dilapidated that the Emperor Frederick III decided to build a new one. This imperial residence stood only for 100 years. Already in 1565 it was rebuilt again. The next expansion was made in the mid-1600s.
Todau Ennsegg castle has two courtyards separated by a longitudinal wing. In the arcades are Roman finds from Lauriacum (Lorch). The castle chapel dates back to the second half of the 17th century. It was installed in a defensive tower. It is richly decorated with stucco decoration. The altar was erected around 1800.
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.
