Appraisal
This impressive and elegant humpbacked multi-arched road bridge retains its early character and form, and is an appealing feature in the rural landscape to the south of Liscooly. It is robustly-constructed in local rubble stone masonry, and its continued survival and use stands as testament to the quality of its original construction. The wide segmental-headed arches and thin piers with V-shaped cutwaters demonstrate a sophisticated level of design and engineering can are clearly the work of skilled masons. The Ordnance Survey Memoirs of 1836 records that Liscooly Bridge was ‘built in the year 1801 at the expense of about £1,100 pounds, raised by Grand Jury assessment. It has five water arches and two land ones to increase the waterway in time of floods’. It is possible that this bridge may contain earlier fabric although no bridge is depicted on Taylor and Skinner road map of 1777-83. It spans the site of an historic strategic fording point of the River Finn. Set in an idyllic location along the Finn Valley, this noteworthy bridge is an integral element of the built heritage and transport history of the local area, and is a feature of some aesthetic quality in the rural landscape to the south of Liscooly. It is one of a number of fine bridges that span the River Finn in Donegal.
