Overview
The two round towers guarding Monea’s entrance carry square, corbelled tops – a Scottish trick for bracing a turret that you’ll find at Claypotts near Dundee and almost nowhere in Ireland except here. That detail gives away who built it: Scottish planters, dropped into Fermanagh at the start of the 17th century. The four-storey shell stands on a low rise in the townland of Castletown Monea, about six miles north-west of Enniskillen, with Lough Erne spreading out beyond the fields. It’s free to visit and unstaffed – and, an important detail, it sits in the middle of a working farm with livestock, so dogs aren’t allowed.
A turbulent history
Before the Plantation of Ulster reshaped the region, this was Maguire ground, one of the Gaelic lordships that held the Lough Erne country. Under the Crown’s plantation scheme the land was granted in 1616 to the Reverend Malcolm Hamilton, later Archbishop of Cashel. Construction began that same year and the house was finished around 1618; the enclosing bawn was added a few years later, about 1622.
The castle’s quiet did not last. During the Irish Rebellion of 1641, Rory Maguire – a descendant of the original Gaelic owners – attacked the stronghold while it sheltered Protestant families. The building survived and stayed occupied. In 1688 the estate passed to Gustavus Hamilton, Governor of Enniskillen, who died at Monea in 1691 after the Williamite Wars. Financial strain forced the Hamiltons to sell in 1704, a fire gutted the interior in the mid-18th century, and by 1750 the place was abandoned. Local folklore still tells of a “weird woman”, Bell McCabe, said to haunt a vault beneath one of the towers.
Architecture and grounds
The surviving structure is a fine piece of early-modern Scottish tower-house design, a style that crossed the Irish Sea with the planters. The rectangular, four-storey block is flanked at one end by two massive round towers with those angular corbelled caps; crow-stepped gables and mullioned windows drive the Scottish look home.
Enclosing the house is a remarkably intact bawn wall, roughly nine feet high and tracing a circuit of about 300 feet. It once protected livestock, a dovecote, and rounded corner flankers, giving a clear sense of the self-sufficient estate that worked here. Beneath the main house, the vaulted ground-floor chamber – once kitchen and cellar – can still be traced through the rubble.
Just off the western edge of the grounds, a rare medieval crannog rises from the water. This artificial island predates the castle by centuries: it is linked to Hugh ‘the Hospitable’ Maguire in the 15th century, and marks the Gaelic occupation of the site long before any Scottish-style tower was raised on it.
What to see and do
- Explore the ruins – walk freely among the walls to take in the four-storey plan, the ornate doorway, and the vaulted cellar. The open setting is good for photography, especially when a low winter sun throws long shadows across the stone.
- Trace the bawn – follow the nine-foot wall around the courtyard for a tangible sense of the defensive perimeter that once ringed the household.
- Spot the crannog – head towards the western shoreline to find it; a quiet moment on the site’s pre-Plantation past.
- Scenic walks – the beech-lined approach and the Lough Erne views make the grounds pleasant for a slow wander and a bit of bird-watching.
There are no guided tours or events here; you explore on your own.
Practical information
- Opening times: seasonal, roughly Feb–Mar and Oct–Nov 10am–4pm, Apr–Sep 9am–6pm, closed December and January. An electric gate at the entrance shuts promptly at 6pm, so plan to be out before it does.
- Conservation work: during recent works the interior of the castle has been closed and parking cut back – check before a long trip if you specifically want to get inside.
- Access and mobility: paths are grass and gravel, so wear comfortable shoes; the uneven flagstones and rubble inside the ruin limit access for anyone with restricted movement. Watch for nettles in the grass around the walls.
- Dogs: not allowed – it’s a working farm with livestock.
- Facilities: none on site, no café, shop or toilets. Bring what you need.
- Parking: a small car and coach area sits beside the entrance; it can fill on summer weekends, and capacity has been reduced during conservation work, so arrive early.
- Getting there: from Enniskillen, follow the A509 north-west towards Monea (about six miles); signage directs you to the parking. Bus users should check local timetables for stops on the A509.

Come between April and September for the longer hours, leave well before the electric gate shuts at 6pm, and leave the dog at home – the farm’s livestock come first, and it’s the one rule the site actually enforces.
