St Stephen of the Abyssinians is a Roman Catholic church located in Vatican City. The church dedicated to Stephen the Protomartyr is the national church of Ethiopia. The liturgy is celebrated according to the Alexandrian rite of the Ethiopian Catholic Church. It is one of the only standing structures in the Vatican to survive the destruction of old St. Peter's basilica, and thus it is the oldest surviving church in Vatican City.
The church was, by tradition, built by Pope Leo I (ca. 400-461). It was rebuilt in 1159 under Pope Alexander III, who also built a monastery for Ethiopian monks next to it.
In 1479, Pope Sixtus IV restored the church and assigned it to the Coptic monks in the city. It was at this time that the name was changed to reflect that it was served by Ethiopians (Abyssinian). It was altered under Pope Gregory XI (1700-1721), and again in 1928.
The façade is in the style of the early 18th century. The 12th century doorway, decorated with the Lamb and the Cross, has been preserved. The church has a single nave with ancient columns along the sides. The most important work of art is a fresco of the Madonna with Child in the Roman style from the 15th century.
References: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.
