The Orkesta Runestones are a set of 11th-century runestones engraved in Old Norse with the Younger Futhark alphabet that are located at the church of Orkesta.
Several of the stones were raised by, or in memory of, the Swedish Viking Ulf of Borresta, who during the 11th century returned home three times with danegeld. The leaders of the three expeditions were Skagul Toste (Tosti), Thorkell the Tall (Þorketill), and Canute the Great (Knútr). This Ulfr also made the Risbyle Runestones in the same region, and he was mentioned on the lost runestone U 343.
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.
