The Hermitage at Ffald y Brenin Christian Retreat Centre

A single storey with loft, rubble-stone former mill under a slate roof in a blend of colours, with stone stack to the L and skylight to the rear slope. Openings are under brick arches, while windows and doors themselves have trapezoidal heads, and windows have slate sills. A half-glazed boarded door is to the R, with 2 unequal windows to its L. In the L gable end is a further window, offset to the R, and in the R gable end, where the ground rises steeply, is an attic window and a small opening in the ground floor.

The interior has white-plastered walls and ceiling. In the ground floor is an inserted fireplace with stone surround made up of unquarried stone, unplastered, with slate hearth slab. A straight stair leads to a ‘croglofft’-type sleeping space.
