The mausoleum was built in 1909 by Edward Lyulph, 4th Lord Stanley. He died in 1925 and it contains his ashes and those of his wife, Mary Katherine, who died in 1929. The mausoleum is built in ashlar buff and red sandstone with a Kerridge stone-slate roof. It was designed in the neo-Jacobean style by Paul Phipps, and is rectangular in shape, with two storeys and a three-bay north front. The central bay contains a door, above which is the Stanley crest, a three-light window and a date plaque in the gable. On the sides of the upper storey are three four-light windows. Inside the mausoleum is a white marble sarcophagus. The yew tree in the churchyard is 1,200 years old.
