St Margaret's Chapel, at Edinburgh Castle, is the oldest surviving building in Edinburgh, Scotland. An example of Romanesque architecture, it is a Category A listed building. Legend had it that St. Margaret worshipped in this small chapel, but recent research indicates that it was built at the beginning of the 12th century by her fourth son who became King David in 1124. The building has been restored and the interior presents much the same appearance as it did when first in use.
