Castle Caldwell | Fermanagh

Overview

Castle Caldwell Forest Park is a 200‑hectare mixed broad‑leaf and coniferous woodland on the northern shore of Lower Lough Erne. The peninsular setting provides sweeping lake vistas, a jetty for water‑based activities and a network of well‑marked forest tracks. The ruins of Castle Caldwell – a 17th‑century Plantation stronghold later transformed into a Georgian estate – dominate the landscape, while the surrounding forest is a haven for walkers, birdwatchers and history enthusiasts alike.

Landscape and Conservation

The forest sits on two promontories that jut into Lower Lough Erne. It is designated as an important conservation forest with several ancient‑woodland indicator species. Management is gradually removing non‑native conifers from the Rossmore and Rossinure areas to restore native broad‑leaf woodland. The site is a bird sanctuary monitored under an agreement with the Royal Society for the Protection of Birds (RSPB), supporting species such as great crested grebes, tufted ducks and reed buntings.

History

Castle Caldwell was erected between 1612 and 1619 by Sir Francis Blennerhasset as a classic Plantation‑style fortified house, featuring a bawn with two semi‑circular flanker towers. In 1662 the estate was purchased by James Caldwell, an Enniskillen merchant, who renamed the property and began extensive garden and fish‑pond works. The Caldwell family were granted a hereditary baronetcy in 1683, and the castle received Gothic flourishes during the late‑18th‑century renovations.

The estate passed to John Caldwell Bloomfield in the early 19th century. Bloomfield, an amateur mineralogist, ordered a geological survey that revealed high‑quality feldspar, kaolin, flint and shale – the raw materials later used to establish the world‑renowned Belleek Pottery.

The castle remained occupied until the early 20th century, after which it fell into ruin. Today the ruins are managed by the Northern Ireland Environment Agency and the Forest Service.

Geology and the Belleek Pottery Connection

John Caldwell Bloomfield’s 1849 survey identified extensive kaolin and feldspar deposits on the estate. Recognising their commercial potential, Bloomfield partnered with Robert Williams Armstrong and David McBirney, secured a rail spur to nearby Belleek and, in 1853, laid the foundation stone for the Belleek Pottery factory. The fine‑white porcelain that emerged from Belleek would later be prized by royalty and collectors worldwide.

Caldwell Chapel and Graveyard

A short walk west of the castle ruins leads to the remains of a small 17th‑century chapel, traditionally identified as the estate’s family chapel. Built around 1690 by Sir James Caldwell, the chapel is rectangular with a rounded‑arch doorway and buttressed east window. It is surrounded by a low stone wall and a modest graveyard containing the burials of several Caldwell family members, including Sir James himself (d. 1716/17), as well as members of the Hamilton and Browne families who served the estate. The graveyard is still visible but the stones are weathered; visitors are asked to treat the area with respect.

Railway Gate Lodge and Other Historical Features

At the southern edge of the demesure stands the former Railway Gate Lodge, erected circa 1866 when a railway spur was built to serve the Belleek Pottery. The castellated lodge once controlled access to the estate via the railway embankment and still retains its arched gateway and stone mullioned windows. Nearby you can also see an early‑19th‑century lime kiln, used to produce quicklime for the pottery, and the octagonal garden temple that once overlooked the lake.

A notable Sitka spruce, planted in the car park in 1921, marks the early forestry planting phase of the 20th century.

All routes are marked with red, blue and yellow arrows and are shown on OSNI Sheet 17 maps. The walks weave through ash, beech, oak and holly woodlands, along the newly exposed foreshore (the shoreline was lowered by about 3 m in the 1880s) and up to the peninsula’s highest points, where the castle’s silhouette dominates the horizon.

Flora and Seasonal Highlights

Spring brings a riot of colour: buttercups, red clover, woodland bluebells and a carpet of mosses. In early summer, the forest floor is dotted with ferns and the lake edge teems with courting waterbirds. Autumn paints the canopy in gold and amber, making the longer Rossergole Point Walk especially scenic.

Wildlife and Birdwatching

The forest forms part of the Lower Lough Erne Nature Reserve, managed by the RSPB. Regular visitors spot great crested grebes, tufted ducks, reed buntings and the elusive Common Scooter. Pine martens and red squirrels are also recorded in the deeper woodland.

Picnic and Water Activities

Designated picnic tables sit near the car park and beside the jetty, making it easy to enjoy a packed lunch while watching boats glide across the lake. The jetty provides access for kayaking, paddle‑boarding and fishing.
