Sir Alan built St Fillan's Church, which still stands, next to the castle, in around 1140, and his family probably built the original hall house in around 1200, or possibly even earlier. In 1216, another Alan de Mortimer is recorded granting land to the monks of Inchcolm Abbey. There is no record of what happened to the de Mortimers, but in the early 14th century, King Robert the Bruce granted Aberdour to his kinsman, Thomas Randolph, Earl of Moray (d. 1332).
