4 Best Sights in Lismore, The Southeast

As you cross the bridge entering Lismore, you spot the magnificent Lismore Castle, a vast, turreted building atop a rock overhanging the River Blackwater. There has been a castle here since the 12th century, but the present structure, built by the 6th Duke of Devonshire, dates from the mid-19th century. The house remains the estate of the Cavendish family, and most of it is not open to the public. You can see the contemporary-art gallery, designed by Cork architect Gareth O'Callaghan, in the west wing, as well as the upper and lower gardens, which consist of woodland walks, including an unusual yew walk said to be more than 800 years old (Edmund Spenser is said to have written parts of The Faerie Queene here), certain months of the year. The gardens have an impressive display of magnolias, camellias, and shrubs, and are adorned with examples of contemporary sculpture.

Leaving Lismore, head east on N72 for 6½ km (4 miles), then north on R669 into the Knockmealdown Mountains. From the summit, called Vee Gap, you'll have superb views of the Galtee Mountains in the northwest and a peak called Slievenamon in the northeast. If the day is clear, you should be able to see the Rock of Cashel, ancient seat of the Kings of Munster, some 32 km (20 miles) away. Just before you enter the Vee Gap, look for a 6-foot-high mound of stones beside the road. It marks the grave of Colonel Grubb, a local landowner who liked the view so much that he arranged to be buried here standing up so that he could look out over the scene for all eternity.

In the former town courthouse, Lismore Heritage Center and its exhibits focus on the town's Celtic origins and its links to famous people from Sir Walter Raleigh to Prince Charles to Fred Astaire. Lismore Experience, an impressive video presentation, charts the history of the town from its monastic 7th-century origins up to the present day, with a virtual reality tour of the castle an additional option. The center also has a large crafts shop, and the Robert Boyle Escape Room is a fun way to uncover the great discoveries of the noted local 17th-century scientist.

The first post-Reformation monastery, Mount Melleray Abbey was founded in 1832 by the Cistercian Order in what was then a barren mountainside wilderness. Over the years the order has transformed the site into more than 600 acres of fertile farmland. The monks maintain strict vows of silence, but you're welcome to join in services throughout the day and are permitted into most areas of the abbey. It's also possible to stay in the guest lodge. There's a small heritage center about the history of Irish monasticism with a few ogham stones and a short film.
