The Tomb of the Eagles, or Isbister Chambered Cairn, is a Neolithic chambered tomb. First explored by Ronald Simison, a farmer, when digging flagstones in 1958, he conducted his own excavations at the site in 1976. Alerted by Simison, archaeologist John Hedges then mounted a full study, prepared a technical report and wrote a popular book that cemented the tomb's name.
16,000 human bones were found at the site, as well as 725 from birds. These were identified as predominantly belonging to the white-tailed sea eagle (Haliaeetus albicilla) and represented between 8 and 20 individuals. These were originally interpreted as a foundation deposit, however this interpretation has been challenged by new dating techniques. These reveal that the eagles died c. 2450–2050 BC, up to 1,000 years after the building of the tomb. This confirms growing evidence from other sites that the neolithic tombs of Orkney remained in use for many generations.
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.
