Although a visit to Nendrum Monastery is fairly straightforward, there are a few need-to-knows that’ll make your visit that bit more enjoyable.

1. Location

Nendrum Monastic Site is located in the middle of Mahee Island on the western side of Strangford Lough. It’s accessed by a series of causeways across to the island and it’s a 35-minute drive from both Bangor and Downpatrick and a 25-minute drive from Newtownards.

2. Parking

There is a decent size car parking area right off the main road at Nendrum Monastic Site (here on Google Maps). There’s room for several cars here on the water’s edge, and the ruins are just a short walk up the hill on a signposted trail.

3. Part of Strangford Lough

Nendrum Monastery is part of Strangford Lough and it’s one of the main attractions on this inlet, which is the largest in Ireland. Mahee Island is just one of 70 islands on the water and one of the few accessible by road. The lake is classified as both an Area of Outstanding Natural Beauty and an Area of Special Scientific Interest for its rich biodiversity and unique flora and fauna. 

The story behind Nendrum Monastic Site

The incredible ruins of Nendrum Monastery have an interesting history that is worth reading up on before your visit!

The island monastery was founded in the 5th century by Mochaoi, who is also known by his proper name Caolan. According to legend, he was said to have been appointed by St Patrick himself. 

Early days

There are references to Nendrum Monastic Site up until the 10th century, when it was suspected to have been pillaged and demolished. 

The next mention of the site was in 1178 when it was under the control of Benedictine monks who founded a small cell on the island.

It was eventually abandoned in the 15th century for a new site at the village of Tullynakill.

The re-discovery and excavation

The location of Nendrum Monastery was lost sometime in the 15th century until it was later discovered in 1844 by William Reeves.

He had visited the island in search of a church that had been recorded in 1306. He recognised the remains of the round tower at the site as the one he had been looking for.

The ruins were excavated by archaeologist Henry Cairnes Lawlor in the 1920s with some of the findings now kept in the Ulster Museum in Belfast.

It was the first major excavation of an ecclesiastical site at the time with extensive reports published about it.

The site then underwent other excavations and restorations over the years until it was left in its current state.

The remaining features and design

The major remains of the monastic site are three enclosures of dry stone walling, which were rebuilt by Lawlor in the 1920s.

The central enclosure has the remains of the round tower, a ruined church, sun dial and graveyard. The second enclosure has what is assumed to be the monastic school. 

The sun dial now in a corner of the church is one of the few early medieval sun dials to still exist and is one of the highlights of a visit.
