Overview
Mount Sandel sits quietly on the eastern bank of the River Bann, roughly 1.5 km south of Coleraine in County Londonderry. At first glance, it appears to be a peaceful woodland walk, but the ground here holds one of Ireland’s most significant archaeological secrets. This is the location of the country’s earliest known Mesolithic settlement, dating back nearly 10,000 years.
Managed by the Mountsandel Discovery & Heritage Group, the site is open year-round and free to enter. You can walk among the stone-lined foundations of ancient hunter-gatherer huts, explore a Norman-era earthwork, and follow flat trails through mixed woodland. It makes a convenient stop on the Causeway Coast route, offering a quiet contrast to the busier tourist attractions further north.
History: From Mesolithic Settlers to Norman Forts
Ireland’s First Homes (c. 7,900 – 7,600 BC)
Excavations led by Peter Woodman in the 1970s uncovered a cluster of wig-shaped huts, hearths, and more than 1,100 flint microliths. These were the homes of Ireland’s first hunter-gatherers, who lived here long before the arrival of farming.
The inhabitants fished the River Bann for salmon and eel, hunted deer, hare, and waterfowl, and gathered hazelnuts, berries, and wild garlic. Analyses of animal bones and shellfish remains reveal a sophisticated, seasonal diet adapted to the post-Ice Age landscape. The stone-lined footprints of these dwellings are still visible today, marked by interpretive panels that explain daily life in this ancient community.
The Norman Earthwork (Late 12th – 13th Century)
A few millennia later, the site saw activity during the Norman period. The prominent mound, often called Mountsandel Fort, is an unfinished Anglo-Norman motte-and-bailey castle. It consists of an oval earth mound surrounded by a deep ditch, designed to support a timber palisade.
Medieval pottery and pipe fragments found nearby indicate brief occupation, but the castle was never fully completed. After falling into disuse, the site was gradually reclaimed by nature. Bronze- and Iron-Age artefacts recovered from the Bann’s alluvial deposits suggest intermittent activity across the centuries, but the forest eventually took over, creating the mixed-species woodland seen today.
Nature and Walking Routes
Mountsandel Wood is designated as an Area of Special Scientific Interest (ASSI), protecting both the archaeological layers and the valuable habitat. The forest is a mix of mature oak, ash, beech, lilac, hawthorn, and wild cherry.
The riverbank and woodland edges support a variety of wildlife. Birdwatchers frequently spot kingfishers, buzzards, grey herons, and mute swans. The paths are flat, well-maintained, and suitable for families, casual walkers, and dog owners.
Key walking loops include:
- View of the River Bann loop: Approximately 3.3 km, taking around one hour. Offers clear views over the river and Somerset Wood.
- Motte and Bailey loop: A longer circuit of roughly 4.7 km that encompasses the historic earthwork and deeper sections of the forest.
- Somerset Forest loop: A shorter 3.2 km walk, ideal for a quick visit.
