Kirkistown Castle is an impressive three-storey tower house, built in 1622 by Roland Savage, a Norman landlord, at the site of a ninth-century round tower. It was occupied until 1731, when it was deserted. It post-dates the Plantation, but is fully in the late medieval tower-house tradition. Parts of the bawn wall survive with three-quarter round flanker towers at the angles. The tower was remodelled in Gothic style in 1800 by a Col. Johnston, and in 1836 some further work was performed by a very young Master Montgomery of Grey Abbey. The building was left, however, with a partial roof and broken windows, and the elements soon returned it to disrepair.
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.
