Strangford Castle appears to be a small tower house from the late 16th century, but a blocked door of 15th century type at first floor level, seems to indicate the remodelling of an earlier tower. The current entrance, in the north-east wall, is a reconstruction, positioned by the surviving corbelled machicolation above and a socket from a draw-bar to secure the original door. The original entrance may have been on the first floor. It is a small, rectangular, three-storey tower house with no vault or stone stairway. The first floor fireplace has an oven. The ground floor chamber is lit only by small gun-loops. The roof has very fine crenellations, again with pistol-loops. The original floors, like their modern replacements, were made of wood.
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.
