Overview
Derrycassan Wood stretches over roughly 179 acres on the north‑eastern shore of Lough Gowna, near the village of Mullinaghta and a short drive from Granard in County Longford. The mixed‑species forest – a patchwork of conifer plantations and native broad‑leaf stands – is managed by Coillte and is freely open to the public. Its gentle esker ridges, riverbanks and open lakeside clearings make it an ideal spot for a relaxed stroll, a family picnic, or a quiet moment of lakeside contemplation.
History
The wood forms part of the former Dopping‑Hepenstall estate, centred on Derrycassan House, a three‑storey mansion built in 1760. The house was surrounded by extensive walled gardens, an orchard and a summer house, typical of an Anglo‑Irish country seat. In 1939 the mansion was demolished; its stone was later reused to build St Columba’s Roman‑Catholic church in the nearby village. Today the low stone walls of the walled garden, a few surviving gate arches, and two stone bridges remain visible, offering a tangible link to the 18th‑century landscape.
Long before the estate, an ancient rath (ringfort) dating from roughly 500–1500 AD lies hidden among the trees, hinting at early settlement in the region. The state forestry service acquired the land in the 1930s and planted the coniferous stands that now dominate the woodland.

Wildlife and Flora
The wood supports around 20 tree species. The most common are Sitka spruce, Norway spruce, Douglas fir, alder, ash, oak, beech, Western hemlock and Western red cedar. In spring the understory erupts with bluebells, periwinkles, elderberry, holly and rhododendron, while willow and alder scrub line the riverbanks. After rain, a variety of fungi appear, and birdwatchers may spot tits, goldfinches and occasional woodpeckers.
