Built in 1828 and first shown on the 1834 town map.


Belongs to a group of 20-26 Segontium Terrace.

A late Georgian terrace of seven 3-storey 2-bay houses with basements, all have rendered fronts while some retain original moulded architraves to the windows and have exposed rubble stone rear walls. Slate roofs are graded to the rear slopes, and each house has a brick or roughcast stack to the R. The doorways are placed on the L sides, and are reached up steps. Many of the houses retain original iron railings on dwarf stone wall, with replaced gates to the basement steps. The railings have trident finials with urn finials to the stanchions.

A roughcast front with replaced windows in original openings, blind upper L, and added open gabled porch with replaced front door and overlight. The forecourt railings have been removed.

Reasons for Listing

20-26 Segontium Terrace is listed as an ambitious urban development prominently sited above Slate Quay. Notwithstanding some loss of its original unified design, the terrace contributes to the strong Georgian tradition in Caernarfon and documents the growing prosperity of the town in the early C19 in the wake of the development of Caernarfon as a major N Wales port. No 24 is listed notwithstanding loss of original detail.
