Appraisal
The Fifth Lock is one of a group of locks at Inchicore, designed to raise or lower boats between different levels of the Grand Canal. The Grand Canal is the southernmost of a pair of canals that encircles Dublin city, and provides a waterway connection between Dublin's River Liffey and the River Shannon. This is one of the earlier locks built in Dublin city, as the canal originally terminated at the City Basin off James's Street, and the circular line was only completed in the 1790s. The canal network developed in the late eighteenth century and encouraged the commercialisation and industrialisation of the country. It is of considerable technical and engineering interest and is constructed of good quality stone and early timber lock gates that retain their early mechanisms.
