Cullerlie stone circle, also known as the Standing Stones of Echt, consists of eight irregular stones of red granite arranged at approximately equal intervals to form a circle of 10.2 m diameter, enclosing the same number of small cairns.
At the time that the circle was built in the second millennium BC, the surrounding landscape was characterised by wet bogs, and the stones were transported to the site from higher ground some distance away. The tallest of the stones marks the north side of the circle. A 2004 survey of the site discovered that several of the stones had been carved with previously unnoticed cup marks.
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.
