Mausoleum to N end of Vaynol Wood, with enclosing wall and railings

The mausoleum at the northern end of Vaynol Wood is built from snecked rubble with freestone dressings and features a banded fish-scale and plain slate roof. It is designed in an Early French gothic style, with a rectangular plan, polygonal ends, and an octagonal belltower located at the north corner next to the gabled main entrance. There are three windows on each side of the structure. The tower has a stone tiled roof with deeply crocketed eaves cornice and similar bands below the open belfry, along with broached buttresses. Other gothic elements include annulets on the foliated shafts and 2-light windows in the apses with quatrefoil oculi. The main door is adorned with notable iron strapwork.

The mausoleum is enclosed by an octagonal wall made of stone, topped with tall cast iron railings. Access is provided through double gates on the eastern side.

Inside, the mausoleum features a remarkably tall open roof supported by hammerbeam trusses that rise from a carved timber cornice. Nook shafts are present at the windows, and a sill band runs around the interior. The three 2-light windows at the eastern end contain good stained glass, possibly created by Powell. Above the doorway leading to the tower stairs, which also descend to a burial crypt below that is now sealed, there is a carved stone tympanum.

The railings surrounding the central monument have been dismantled. There are slate tablets commemorating Enid Mary Archdale Porter [Duff Assheton-Smith], who died in 1919, and Laura Alice Holdsworth and G.W. Assheton-Smith, who died in 1940.
