The Earl"s Palace is a ruined 16th-century castle. It was built by Robert Stewart, 1st Earl of Orkney (1533–1593), illegitimate son of King James V and his mistress Euphemia Elphinstone.
The castle was constructed in two phases. The first phase of work, begun in the 1570s, consisted of the great hall located in the south range, above the main door. Beside this was Lord Orkney"s private chamber in the south-east corner tower. An inscription above the entrance, dated 1574, marks this phase. The second phase, completed in the 1580s, saw a new range containing a great hall and chamber built on the north side of the courtyard. The second phase probably followed Robert"s acquisition of the Earldom of Orkney in 1581. After the death of Robert Stewart, the palace was used only occasionally by later earls of Orkney, and was not occupied after the mid-17th century. By 1701 the palace had begun to deteriorate badly.
The two-storey palace was constructed around a central courtyard and well, with large stone towers at three of the four corners. It was as much a fortress as a residence. Only the palace"s upper floors had large windows; the accessible ground floors were equipped with small openings and an array of gun-holes, from which musketeers could cover every side of the building.
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.
