Churchyard walls, lych gate and railings enclosing Mostyn burial ground at Llanrhos church

A rubble-stone lych gate with slate roof behind coped freestone gable. Entrances have a segmental arch with voussoirs. On the S side is a contemporary iron gate with spear finials to broad main and dog bars. The standards have cast iron urn finials. Inside, the walls are pebble-dashed, with wooden benches. Abutting the lych gate on the W side are stone and slate steps to a mounting block.

The churchyard wall is rubble stone. From the lych gate it continues across the W side of the churchyard, facing Conway Road. In this section is a central recessed entrance with monolithic gate piers, and double gates similar to the lych gate, of which only the L-hand standard retains an urn finial. A flat-roofed shed has been built on the NW corner (close to the site of the former Queen's Head). The wall continues on the N side of the original churchyard (later extended on the other side), and terminates opposite the end of the chancel.

From the lych gate the wall continues E and bounds the S side of the churchyard. In this section is a wrought-iron gate similar in style to the lych gate, with urn finial retained on the R standard. Beyond the gate the wall is a later extension, evidence for which is a vertical joint, and returns on the E side of the churchyard. The E wall is stepped out at the NE end around on the Mostyn burial ground. On the inner side of the wall the burial ground is enclosed by iron railings of 9 bays. Of these, bays 2-4 are set well forward. The cast iron railings have cusped arcading, including inverted lower arches, and fleur-de-lis finials. Octagonal standards have diagonal buttresses, and pyramidal caps rising from castellated capitals. Bays 3 and 5 have double gates of similar design, and each has a rectangular panel with the monogram 'M' in archaic lettering.

The following items form a group: the Church of St Hilary, Churchyard walls, lych gate, south and wet gates to Churchyard, railings enclosing Mostyn burial ground, mounting block to south-west of lych gate and wall on eastern and south-eastern sides of car park to south of Churchyard, including drinking fountain and gate.
