In 1722, the 11th Lord Lovat raised the roof of the mausoleum and constructed a tower overhead. After his execution for the part he played in the Jacobite rebellion, legend had it the Lord Lovat's body was moved in secret, from the Church of St Peter ad Vincula in London to the family mausoleum. However, analysis of his supposed skeleton by the University of Dundee in 2018, declared the bones were of a young woman.
