Ratho () is a village in the Rural West Edinburgh area of Edinburgh, Scotland. Its population at the 2011 census was 1,634 based on the 2010 definition of the locality. It was formerly in the old county of Midlothian. Ratho Station, Newbridge and Kirkliston are other villages in the area. The Union Canal passes through Ratho. Edinburgh Airport is situated only 4 miles (7 km) away. The village has a high ratio of its older houses built from whin stone due to a whin quarry nearby. The older, historical, part of the village was designated a Conservation Area in 1971 by Midlothian County Council. Origins Ratho appears in written records from 1243 with various spellings such as Rath (ewe, eu, ew, ow, au) but most consistently, from 1292, with its present name Ratho. Other places nearby having "Ratho" in their names include Ratho Byres, Ratho Park and Ratho Bank (now named Ashley). It is believed that the name Ratho comes from Rath, Scottish Gaelic, for a place where there are hill forts. Both Kaimes and Dalmahoy hill forts are nearby. To the southwest of the village, Tormain Hill is the site of Stone Age symbols carved into the rocks atop the hill and a 'witches' stone'. When the witches' stone was moved by the land owner for farming, it was believed evil spirits were released into the village. Haltoun House There are a number of old buildings in the area. The most prominent of these was Haltoun House or castle (pronounced, and sometimes spelt, Hatton), which was badly damaged by fire in the mid-1950s and subsequently taken down. This magnificent country house evolved from its central core, a Norman keep, or what Scots call a Pele Tower. In 1371 the manor and lands of Haltoun were resigned to the Crown by John de Haltoun, and were regranted to Alan de Lawedre [Lauder] of that Ilk who then resided mostly at Whitslaid Tower just outside Lauder. Haltoun Tower was damaged during the House of Douglas troubles of 1452, when a note in the Treasurers' Accounts show funds being provided for its repair. The Haltoun estates remained in the Lauder family until the latter half of the 17th century when they passed by marriage to Charles Maitland, 3rd Earl of Lauderdale, who enlarged and beautified Hatton House. Parish Church (St Marys) There is evidence of a pre-Norman, Celtic church on this site,
