Hen Wrych Lodge including adjoining crenellated boundary walls and towers

The Hen Wrych Lodge comprises a twin-arched entrance flanked by square, battlemented towers, constructed of local limestone rubble with limestone dressings. The lodge and associated boundary walls, towers, and cart house date to the 19th century.

The adjoining walls begin in the east with a small, round turret featuring a corbelled parapet, a feature not shown on the first edition Ordnance Survey map of 1873. A blocked pointed arch doorway with a blocked slit-light is located 10 metres east of the turret. Beyond this are the two four-centred arch gateways, set back between taller square towers with deeply corbelled parapets, in a machicolated style, incorporating diagonal corbelling at the corners. A lower, similar parapet surmounts the gateways; the left-hand gateway provides access to the castle, and the right-hand gateway leads to the forecourt of Hen Wrych. A limestone shield with cast iron rosettes is centrally positioned above the gateways. Contemporary plain iron half-gates remain at both entrances. The left tower incorporates a house and has three small-pane, cast-iron windows to the rear (facing the entrance front). The rear of the right-hand tower originally featured camber headed doorways and four-centred arch window openings, though the cast-iron glazing, by Rickman, was recently removed in 1997.

Twenty metres west of the gateways, the wall descends at a masonry break where a square tower with a corbelled, though unbattlemented, parapet abuts, flush with the walls to the front. The wall continues downwards, joining a further, similar tower, which has been heightened. This tower is integrated into Nursery Cottage, a modern house built at the rear and abutting the wall. Immediately to the left of this tower is a blocked, small pointed-arched doorway. Further west is a broader, also blocked (with breeze blocks) entrance, together with another masonry break, leading to a section of crenellated wall terminating in a flush bastion at the westernmost corner of the walled gardens. A recent low roadside wall continues up to a broad gated entry to the former gardens.

Adjoining the north (inner) side of the wall, west of the westernmost gate tower and terminating at the first bastion, is a five-bay lean-to cart house. Tudor arches are present across the bays, except for the most eastern bay, which has been converted into a modern carport with a slated roof projecting forward. Bay four retains slating, while the remainder is covered with corrugated iron.
