Malcolm's Tower is a traditionally accepted as a historic site in the Scottish town of Dunfermline. The tower stood on a highly defensible peninsular outcrop of rock above a deep ravine and is the site from which the city derives its name. It was effectively the seat of royal power in Scotland after Malcolm III of Scotland shifted the centre of government from Forteviot to Dunfermline in the mid 10th century. The site was also close to a religious centre which had begun as an Culdee establishment in the 9th century. The first mention of the tower in the historical record is from 1070 when Malcolm III married his queen, Princess Margaret. As queen, Margaret introduced innovations which changed the course and identity of the Church in Scotland.
