Cadw's description
Summary description and reason for designation
The following provides a general description of the Scheduled Ancient Monument.
The monument consists of the remains of a bridge, dating to the post-medieval period built by Sir Benjamin Hammet in 1799 to carry the Llechryd to Boncarth road over a canal that had been newly built in 1772 and which supplied power to the Castell Malgwyn Tinplate Works (1772-1806). The single span rubble stone bridge with a flat slate-coped parapet has a shallow cut stone arch. Above the voussoirs is an arch-ring string course. There are two iron plaque keystones on either side recessed into the masonry. Both have a representation of a castle on the top, and crossed canons on the bottom, one bears the inscription Castle Maelgwyn 1799, the other Sir Benjamin Hammett.
The monument is of national importance for its potential to enhance our knowledge of post-medieval construction techniques and transportation systems. It retains significant archaeological potential, with a strong probability of the presence of associated archaeological features and deposits. The structure itself may be expected to contain archaeological information concerning chronology and building techniques.
The scheduled area comprises the remains described and areas around them within which related evidence may be expected to survive.
