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 Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
