History Carlingford and Newry Portadown canals
Carlingford
The town of Carlingford, Ireland, has a rich and complex history dating back to the Viking invasions in the 9th century. The town's name itself is of Scandinavian origin, meaning "Fjord of Carlinn." However, the true founders of the town were the Normans, who recognized the strategic importance of Carlingford Lough as a gateway to Ulster.
In the 12th century, the Norman knight Hugh de Lacy laid the foundation for a castle on a rocky outcrop. This fortress, now known as King John's Castle after King John's visit in 1210, became a vital defensive point for centuries. A settlement grew up around the castle, and Carlingford's position as a major trading port led to prosperity throughout the 14th to 16th centuries. This wealth is still evident today in the remains of fortified townhouses like The Mint and Taaffe's Castle.
However, the town's prosperity was not permanent. Raids by Scottish forces, the 1641 Rising, the Cromwellian Conquest, and the Williamite wars all took their toll on the local economy. The final blow came in the 18th century when the prosperous herring shoals left the lough.
Carlingford's inability to develop heavy industry, ironically, helped preserve its medieval layout and archaeological artifacts. In the late 19th century, the Dundalk, Newry and Greenore railway opened, bringing a new era of tourism to the area. Today, tourism is a key part of Carlingford's economy, with visitors drawn to its medieval streets, historic sites, and scenic beauty. The town is also famous for its oysters and hosts an annual oyster festival. The town also hosts stag and hen parties which have become commonplace in very recent years.

Greenways
The Carlingford Greenway is a popular walking and cycling trail that follows the route of a disused railway line, the Dundalk, Newry & Greenore Railway. The railway, which was a vital part of the area's infrastructure and a key driver of tourism in the late 19th and early 20th centuries, closed in 1951.
The vision for a modern greenway to connect communities and encourage active travel began to take shape in the 21st century. The project was a cross-border initiative, with different sections being developed by Louth County Council and Newry, Mourne and Down District Council.
The development of the greenway happened in several phases:
-
Phase 1 (2012): The first section of the greenway, a 7km stretch between Carlingford and Omeath, was opened. This part of the trail quickly gained popularity among locals and tourists.
-
Phase 2 (2018): A second section, approximately 5.7km long, opened in July 2018. This part of the greenway runs from Newry to Victoria Lock, following the Newry Ship Canal and the Newry River.
-
Final Sections (2024-2025): The final, and most challenging, sections of the greenway were completed, connecting the previously opened parts. A new extension from Omeath to the border of the Ireland and Northern Ireland opened in June 2024. The final link, a 1.2km boardwalk and 0.5km greenway connecting Victoria Lock to the border, was a technically complex part of the project. It faced delays due to planning permission and funding issues, but was ultimately completed in 2025, finally creating a continuous cross-border route between Carlingford and Newry.
The Carlingford Greenway is a key part of the larger vision for "The Great Eastern Greenway," which aims to create a long-distance, off-road path along the east coast of Ireland. The greenway is a testament to effective cross-border cooperation and has become a valuable recreational and tourism asset for the region.
Newry Ship Canal
​
The Newry Ship Canal was opened in 1769 to provide a navigable link between Newry town and Carlingford Lough. Unlike the earlier Newry Canal (1742), which connected Newry with Portadown and the River Bann, the Ship Canal was designed to accommodate larger vessels and give Newry direct access to the sea.
Stretching for about five miles, the canal was built along the course of the River Clanrye and included several bascule bridges and a sea lock at Victoria Lock to manage tidal flows. This development allowed ships to travel inland as far as Newry’s quays, turning the town into a thriving port and trading hub during the 18th and 19th centuries. Coal, timber, grain, and linen were exported and imported in growing quantities, strengthening Newry’s position as one of Ireland’s leading provincial ports.
The arrival of the railways in the mid-19th century gradually reduced the canal’s importance, though it remained in use into the 20th century. Commercial traffic eventually declined, and shipping ceased altogether by the 1970s.
Today, the Newry Ship Canal survives as an important heritage and recreational waterway. Victoria Lock has been restored, and the canal is now used for leisure boating, walking, and tourism, keeping alive the legacy of a waterway that once helped put Newry on the map as a centre of trade and industry.
Portadown to Newry Canal
​
The Portadown to Newry Canal, better known as the Newry Canal, holds the distinction of being the first summit-level canal ever constructed in the British Isles. Completed in 1742, it was a landmark feat of 18th-century engineering and played a crucial role in the commercial development of Ulster.
The canal was designed to link the River Bann at Portadown with Carlingford Lough at Newry, creating an inland navigation route that allowed coal from Tyrone and agricultural produce from Armagh and Down to reach markets and ports more efficiently. By joining the Bann to the Irish Sea, it also offered a direct waterway connection between Lough Neagh and the coast. At the time of its completion, the canal stretched around 18 miles (29 km) and included numerous locks to overcome height differences in the landscape.
Built largely under the direction of engineer Thomas Steers and later Richard Cassels, the project represented a bold vision of economic improvement. For over a century, the canal facilitated the transport of coal, linen, timber, and foodstuffs, fostering trade in both rural and urban areas. The town of Newry, in particular, thrived as a commercial hub thanks to this waterway.
However, by the mid-19th century, the rise of railways began to eclipse canal transport. Rail was faster, more reliable, and less dependent on weather conditions. As a result, the Newry Canal gradually fell into decline. Commercial traffic dwindled, and by the early 20th century the canal was largely abandoned as a trading route, though it remained officially open until 1949.
The canal has not been maintained in recent years but the tow path has been converted into a walking and cycling path with excellent underfoot conditions. It is signposted all the way and follows the western side of the canal. It now connects with the Carlingford to Newry greenway through the town of Newry.
