RT remote sensing image T1 Port Oriel Harbour, County Louth (Minor Harbours of Ireland) A1 Shotton, Elizabeth, 1959- A1 Semar, Aoife A1 Lennon, Donal A1 Irish Research Council PB University College Dublin PP Dublin, Ireland YR 2019 NO Biographical/historical information: The first documented promoter of Clogher Head Harbour, Wallop Brabazon (1770-1831), described the natural basin on this site as first being enlarged as a haven for local fishermen by James Ussher (1581-1656), Archbishop of Armagh and Lord Primate of Ireland (1625-1656) prior to his departure from Ireland in 1640 (OPW 1827-1885). Though no evidence of this has been found, the land was in the ownership of the Lord Primate until the late 19th century, which lends the tale some credibility (Anon. 1869). Clogher Head was also marked on sea charts in the 18th century suggesting the basin was use by local fishermen at this time (Pratt 1760). From 1825 to 1831, Brabazon promoted the enlargement of the basin, first through private subscription from local gentry including the Newcomen and Foster families, then by a grant from the Commissioners of Irish Fisheries in 1827 (OPW 1827-1885). These works deepened the entrance and basin and extended the basin eastward through excavation of the bedrock. Plans by James Donnell for the Irish Fisheries included a proposal for a future pier and breakwater, which Brabazon chose to complete in 1829 using unmortared vertically set greywacke stone and funded by private subscription, which included donations from the Lord Primate, John Godley, principal tenant on the land and the Foster family in addition to others (ibid). Based on this private subscription Brabazon petitioned for an additional grant for further excavation work in 1830 but, despite support from Donnell, it was 17 years before the work was finally funded and undertaken by the Board of Public Works under the authority of Richard Griffith in 1847 (OPW, 1847-1883). The works in 1847, instigated by a petition by the local community and gentry, followed in principle Brabazon's last petition, consisting of further excavations at the entrance as well as widening and extending the basin southward and eastward. The gentry who had sponsored the petition supported a change of name to Port Oriel, in honour of Baron Oriel, and, though challenged by the local community it was ultimately passed (ibid). The final comprehensive excavations in 1874-78, which included substantial excavations to the west of 180 feet, were designed by William Forsyth C.E., Chief Engineer to the OPW, and undertaken by Martin Farrell and, latterly, Robert Manning of the OPW (ibid). The original 'pier' built by Brabazon remains largely intact, though covered in part by later works in concrete from the 20th century. This structure was not a pier, but rather a quay. The first true pier built at Clogherhead was sponsored by a petition of 1879, inspired by a proposal by Richard Griffith in 1827 for an extensive pier (ibid). Though unsuccessful, it led to the design for a concrete pier by Robert Manning, Chief Engineer of the OPW, in 1885 which included additional excavation works to the basin (ibid). By 1935 Louth County Council had built a form of gate to the basin entrance to secure the boats during storms, and concrete was cast against much of the basin walls to regularise their surface and provide quays (Louth County Council, 1935). In the 1960s the Council demolished part of the original east slip in the basin to extend a concrete quay (Louth County Council, 1938 - 1968). In 2007 a new pier, designed by RPS Engineers, was built over the existing pier using sheet steel piling finished with a concrete deck and parapet wall, with X-Bloc armour on seaward face (Van Den Berge et al., 2007).
