Remains of the medieval Dominican priory on the west side of Carlingford, recognisable by its high, narrow windows and the elongated ruin wing in grey stone. The site lies quietly just outside the centre, with views of the hills and the open grass around the old priory walls.

This charming seaside town overlooks the Mourne Mountains, whose silhouette rises along the coast of Northern Ireland. Carlingford is very lively at weekends thanks to its many pubs and restaurants, which attract visitors from the north, and is famous for its oysters. The village has several historical sights, such as the small King John's Castle, with its romantic silhouette overlooking the sea, and Taaffe's Castle, a former 16th-century merchant's house located a little further from the quay.

The Tholsel is undoubtedly one of the most unique structures in the heart of Carlingford. This medieval city gate, originally built in the 15th century, is the only remaining gate from the original town wall and served for centuries as the ceremonial and administrative entrance to the town.

Once you leave the city of Newry behind, you cycle towards tranquility on An Bealach Glas, also known as the Carlingford Lough Greenway. This flat, smoothly asphalted path follows the banks of the canal and offers spectacular views of the river's mudflats along the way, where you can spot numerous wading birds and sometimes even a stray seal. The route is a true sensory experience: the salty sea air blows towards you while the mountains seem to get closer and closer. The absolute endpoint of this section is the historic Victoria Lock, an impressive lock complex from 1850 that marks the transition from the canal to the open waters of Carlingford Lough. It is the perfect place to get some fresh air and enjoy the maritime dynamics before continuing your journey to the coast.

Saint Patrick and Saint Colman's Cathedral is the architectural jewel of Newry and one of Ireland's most impressive Neo-Gothic structures. Construction began in 1825, and upon its completion in 1829, the cathedral made history as the first Catholic cathedral to open in Ireland following the repeal of the penal laws (Catholic Emancipation). Built from local granite from the nearby Mourne Mountains, this edifice exudes a robust yet elegant power. The cathedral is world-renowned for its fabulous interior: the walls and ceiling are adorned with colourful mosaics, meticulously applied by hand by Italian master craftsmen in the early 20th century. For the cyclist, this is not only a visual highlight along the route but also a place of serene tranquility. Its detailed stained-glass windows and monumental tower make it one of the city's most photographed locations and a worthy endpoint (or starting point) for your tour along the Newry Canal Towpath.

Here you will be treated to a magnificent view of the cathedral. The imposing tower of Saint Patrick and Saint Colman rises majestically above the city, dominating the skyline with its neo-Gothic architecture. This cathedral, completed in 1829, is unique as it was the first Catholic cathedral built in Ireland after the relaxation of the penal laws. From this point, you can see the beautiful texture of the local granite from the Mourne Mountains, from which the church is built.

Taaffe's Castle is a fortified merchant's house dating from the early 16th century, built by the wealthy Taaffe family, who later became the Earls of Carlingford. Situated near the old harbour, the building originally served as a trading post on the ground floor with residential floors above. The architecture displays typical defensive features such as machicolations, narrow loopholes, spiral staircases, and multi-level garderobes. [curiousireland.ie], [castles.nl], [carlingfor...centre.com] The main structure is a four-storey rectangular tower, later extended with a 16th-century northern extension. Its location and construction clearly demonstrate Carlingford's importance as a thriving trading town during that period. After the 17th century, it fell into disuse, and eventually fell into disuse. Today, it forms part of a pub complex and remains a striking example of medieval urban defensive architecture in Carlingford.
