One of a series of bridges erected over side streams for the 17-km Lake Vyrnwy perimeter road, c.1890. Straddles the pool at the foot of Pistyll y Ceunant.


A single-arch bridge with a span of about 12 m, faced in sneck-coursed, rock-faced masonry, although the
interior of the arch appears to be in brick. Voussoirs about 0.8 m in height, and a very large rock-faced
keystone projecting slightly below the intrados, but not quite touching the string course. The string
course at the base of the parapet wall and the coping are both chisel-drafted at the margins and rough-hewn.

Carriageway about 5 m wide.

Reasons for Listing

One of a set of bridges, in various monumental styles and evidently designed by different hands, related to
the exploitation of the Reservoir perimeter road for its touristic potential, and closely related to the
management of the Reservoir estate.
