Killaspugbrone Church and Loop Trail

Overview

Killaspugbrone Church sits at the north-west tip of the Coolera peninsula, just beyond the resort village of Strandhill in County Sligo. The Irish name Cill Easpaig Bróin translates to “the church of Bishop Brón”, honouring Bishop Brón mac Icni, a 5th-century cleric and contemporary of St Patrick. The surviving stone structure faces Coney Island across a wide sweep of sand, while the flat-topped silhouette of Ben Bulben and the rounded slopes of Knocknarea anchor the inland horizon. Today, the ruin serves as the anchor for the Killaspugbrone Loop, a 7 km coastal trail that pairs early Christian heritage with active Atlantic habitats.

History & Local Legends

The site has been a place of worship for over a millennium. Archaeological evidence points to an earlier monastic enclosure, originally called Caiseal Irrae, before the current rectangular nave was built between c.1150 and 1220. The church survived repeated Viking incursions along the Sligo coast and remained an active parish church well into the 16th century.

Local tradition ties the site to St Patrick himself. Legend says the saint lost a tooth here, which was later preserved as Fiacail Pádraig (Patrick’s Tooth). The relic was housed in an ornate 14th-century gold and silver casket commissioned by the lord of Sligo, Thomas de Birmingham, before eventually being acquired by the state. Visitors can view the casket in Dublin’s national museum collections.

The one-acre walled graveyard surrounding the church holds roughly 700 burials. Most markers are simple, weathered slabs that predate the 16th-century shift to upright headstones. One stone records a local man who lived to 102, and the final burial took place in 1961. Across a narrow tidal inlet lies Dúnán Padraig (Patrick’s Little Fort), a rocky islet that folklore claims the tide never fully covers, making it a reliable subject for coastal photography.

The Killaspugbrone Loop Trail

The loop begins at the northern end of Strandhill’s seafront promenade and follows purple arrows on white discs for the full 7 km circuit. The route is graded moderate and typically takes around two hours at a steady walking pace.

• Strandhill to Domin’s Strand: The trail heads north along the promenade, passing local cafés and shops before reaching Domin’s Strand. This broad stretch of sand and shingle is excellent for birdwatching, but the path can flood at high tide. Checking tide times before setting out is essential.
• Dunes and Salt-marsh: Beyond the beach, the path climbs into a protected dune system. Marram grass stabilises the sand, while salt-marsh pools attract waders like curlews, dunlins, and oystercatchers. A low concrete barrier helps prevent erosion and keeps walkers on stable ground.
• Sligo Airport perimeter: The loop skirts the outer edge of the Sligo Airport runway. You’ll occasionally spot light aircraft taking off or landing against the backdrop of Sligo Bay. The contrast between early-Christian stone and modern aviation is one of the trail’s most distinctive features.
• Headland return: The final stretch follows a gentle ridge above the water, offering uninterrupted views back toward Strandhill and the peninsula’s southern coast. The path reconnects with the promenade near the northern car park.

Practical Information

Visitor Tips

• Start early in the summer months to secure parking and catch the soft morning light, which works best for photographing the ruins and Dúnán Padraig.
• Always check the tide tables before walking Domin’s Strand. Incoming tides can cut off the return path along the shingle.
• The ruins and dunes are fully exposed to Atlantic wind and rain. A waterproof layer and sturdy footwear are advisable year-round.
• Stay on marked trails through the dune system to protect fragile vegetation and nesting birds.
• Keep dogs on a short lead, especially near the airport perimeter and in the graveyard.
• If you want to extend your walk, the Benbulben Forest Walk is a short drive inland, while Bunduff Strand offers a quieter Blue Flag beach just west of the peninsula.
