Mountain Castle Bridge — Millstreet matters for the exact reasons given in its official assessment, rather than merely because it is an old structure. The source records: An elegantly-proportioned bridge built by John Sheehan (n. d.) to designs prepared by the engineer Charles Tarrant (1815 – 1877). The construction in limestone serves to assimilate the composition into the surrounding landscape, while the civil engineering heritage importance of the bridge is identified by the profile of the arches, which have retained their original shape. This explains what the place adds to local life, the street or the surviving built history.
