The Trentham Mausoleum is a Grade I listed mausoleum in Trentham, Stoke-on-Trent, built as the final resting place of the Dukes of Sutherland^[1] from the Leveson-Gower family.

The mausoleum was built in 1807–08 for George Leveson-Gower, the 2nd Marquess of Stafford and later 1st Duke of Sutherland by architect Charles Heathcote Tatham.^[2] Heathcote Tatham was a friend of Elizabeth, the Duke's wife, and along with his commission he constructed several buildings, including a lodge and bridges, at the nearby Trentham Hall.^[3]

The mausoleum is constructed in ashlar in a neo-classical style with Egyptian details.^[3] The corners of the building feature striped Greaco-Egyptian pylon-like structures, which may have been influenced by Heathcote Tatum's time in Paris, where the style was particularly popular in the late 18th century.^[4] The entrance doorway is relatively small with doors decorated in highly ornate wrought-iron work and a heavy stone lintel.^[2][3] The mausoleum is surmounted by a small tower, with louvred windows and a pyramidal roof.^[2]

Above the doorway is the family coat of arms and the inscription "MDCCCVIII", signifying the completion date of 1808.^[2]

The condition of the building has given cause for concern, and although some urgent repairs have been completed, as of 2021^[update] it is on the Heritage at Risk Register.
