The Dwarfie Stane is a megalithic chambered tomb carved out of a titanic block of Devonian Old Red Sandstone located in a steep-sided glaciated valley between the settlements of Quoys and Rackwick on Hoy island.
The attribution as a tomb was originally based on its resemblance to recognized tombs in southern Europe. The Dwarfie Stane is the only chambered tomb in Orkney that is cut from stone rather than built from stones and may be the only example of a Neolithic rock-cut tomb in Britain. However, despite its unique construction, its plan is consistent with the so-called Orkney-Cromarty class of chambered tomb found throughout Orkney. Some authors have referred to this type of tomb as Bookan-class, after a chambered cairn in Mainland, although there's some disagreement as to the relationship between the two tomb types.
A stone slab originally blocked the entrance to the tomb on its west side, but now lies on the ground in front of it. It is unique in northern Europe, bearing similarity to Neolithic or Bronze Age tombs around the Mediterranean. There is no direct evidence, however, of any link to the builders of the Mediterranean rock-cut tombs.
The stone is 8.6 metres long, by 4 metres wide and up to 2.5 metres high. Inside the tomb is a passage 2.2 metres long and two side cells measuring 1.7 metres by 1 metre.
The tomb has been plundered by making an opening through the roof of the chamber. The time of this event is not known, but the hole in the roof had been noted by the 16th century. The hole was repaired with concrete in the 1950s or 1960s.
The name is derived from local legend that a dwarf named Trollid lived there, although, ironically, the tomb has also been claimed as the work of giants. Its existence was popularised in Walter Scott's novel The Pirate published in 1821.
References:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
