At Knap of Howar on the island of Papa Westray, a Neolithic farmstead may be the oldest preserved stone house in northern Europe. Radiocarbon dating shows that it was occupied from 3700 BC to 2800 BC, earlier than the similar houses in the settlement at Skara Brae on the Orkney Mainland.
The farmstead consists of two adjacent rounded rectangular thick-walled buildings with very low doorways facing the sea. The larger and older structure is linked by a low passageway to the other building, which has been interpreted as a workshop or a second house. They were constructed on an earlier midden, and were surrounded by midden material which has protected them. There are no windows; the structures were presumably lit by fire, with a hole in the roof to let out smoke. Though they now stand close to the shore, they would have originally lain inland. The shore shows how the local stone splits into thin slabs, giving a ready source of construction material.
Looking back through the low entrance doorway into the main house, a visitor's backpack gives an idea of scale.
The walls still stand to an eaves height of 1.6 metres, and the stone furniture is intact giving a vivid impression of life in the house. Fireplaces, partition screens, beds and storage shelves are almost intact, and post holes were found indicating the roof structure.
Evidence from the middens shows that the inhabitants were keeping cattle, sheep and pigs, cultivating barley and wheat and gathering shellfish as well as fishing for species which have to be line caught using boats.
Finds of finely-made and decorated Unstan ware pottery link the inhabitants to chambered cairn tombs nearby and to sites far afield including Balbridie and Eilean Domhnuill. The name Howar is believed to be derived from Old Norse word haugr meaning mounds or barrows.
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.
