Overview
Dunganstown Castle sits on a gentle rise in the townland of Dunganstown west, just outside the coastal town of Arklow in County Wicklow. The site is dominated by a solitary square tower, its stone walls draped in ivy, that hints at a once‑imposing fortified house built around 1610 by Sir John Hoey. The surrounding estate once stretched across a vista of woodland, a long tree‑lined avenue, and a deer park that faced Castletimon Hill. Today the castle remains in private ownership and is not open to the public, but the Dunganstown Heritage Trail, marked on local maps, allows walkers to experience the ruins from the public right‑of‑way and to explore the rich natural and cultural landscape that surrounds it.
History
The name Dunganstown derives from a wealthy Dublin merchant, Dongan, recorded in 1542. In the 16th century the property passed to the Hoey family, who erected the fortified house that forms the core of the present ruin. Sir John Hoey’s 1610 construction replaced an earlier medieval structure and reflected the turbulent era of plantation and rebellion in Ireland.
Samuel Lewis’s Topographical Dictionary of Ireland (1837) recorded the castle as the property of the co‑heiresses of the late F. Hoey, then occupied by M. Wright, noting that “the only remains are one square tower and an extensive range of domestic buildings, partially covered with ivy.” The tower is described as 14½ ft (≈4 m) square, about 60 ft (≈18 m) high, with walls four feet thick.
Earlier accounts suggest the site may have originated as a Norman stronghold later taken over by the Knights Templar; after the suppression of the Templars it passed to the Hospital of St John of Jerusalem. Welsh slates were reportedly used for the roof, and the tower’s level has sunk some 13 ft (≈4 m) over the centuries.
The castle attracted a parade of notable visitors. King James II is said to have rested in the garden on a “wishing chair” after his retreat from the Battle of the Boyne in 1690. Sir Francis Bacon, Lord Effingham (High Admiral of the English fleet) and Sir Walter Raleigh are also linked to occasional stays. Local legend tells of two underground tunnels – one leading to St Kevin’s Church and another reputed to reach the Black Castle six miles away.
During the 1640s rebellion the tower house was badly damaged; a contemporary witness, Robert Kennedy, recorded its destruction in 1642. The castle was never fully rebuilt, and the ruins we see today are the remnants of that turbulent period.
Surrounding Landscape and Gentlemen’s Seats
Lewis also noted that the surrounding scenery is “pleasingly diversified, embracing extensive mountain and sea views.” The Dunganstown estate lay among a cluster of 18th‑century gentlemen’s seats and villas, including West Aston (the residence of Lieut‑Colonel Acton), Oatlands (W. Shepard), Sheep Hill (W. Shepard), Sea Park (J. Revell), Ballymoney (W. Revell), Ballinclare (Capt. T. Keoghoe) and Springfield (J. Wright). These historic homes contributed to a landscape of cultivated parkland, tree‑lined avenues and views across the Irish Sea, many of which can still be glimpsed from the heritage trail.
Legends, Tunnels and the ‘Wishing Chair’
Beyond the documented visitors, folklore adds intrigue to Dunganstown. The “wishing chair” – a high‑arched garden chair with a carved head at its apex – is said to be the seat on which King James II wept after the Battle of the Boyne. Two subterranean passages are reputed to run from the castle: one to the nearby St Kevin’s Church and a second extending roughly six miles to the Black Castle on the coast. While no archaeological work has confirmed these tunnels, they remain a popular element of local storytelling and guide‑book narratives.
Irish‑Built Fortified House on Colonial Ruins
An Irish Independent feature (2012) argues that Dunganstown Castle was likely erected on the foundations of earlier colonial ruins, a pattern seen elsewhere in Wicklow where Irish landowners adapted Norman or earlier structures for their own fortified houses after 1606. This interpretation aligns with the earlier suggestion of a Norman origin and later Templar ownership, underscoring the layered history of the site.
Coast‑guard Station at Jack’s Hole
The 1837 topography also records a coast‑guard station at Jack’s Hole, one of seven in the Gorey district. The station, situated a short distance south of the castle, was part of early 19th‑century maritime safety efforts and adds another historic point of interest for walkers exploring the coastal stretch between Dunganstown and Brittas Bay.
What to See & Do
The Tower and Long Avenue
The most striking feature is the square tower, its stonework still visible despite centuries of weathering. From the tower’s base, the “Long Avenue” – a wide, tree‑lined vista originally designed to frame views of Castletimon Hill and the former deer park – can be traced along a public footpath. The avenue offers a rare glimpse of 17th‑century landscape design.
Rare Trees and Woodland Walks
The estate’s woodland hosts several extraordinary trees. A 400‑year‑old Hornbeam, reputed to be the oldest living exotic tree in Ireland, stands as a silent witness to the 1641 rebellion, the Cromwellian wars, the 1798 uprising and the Great Famine. Around 1740, a group of ancient yew trees were planted; a Yew Tree Walk now links the castle ruins to the nearby Dunganstown Church, providing a tranquil route for walkers.
Dunganstown Church and Knights Templar Legacy
Just a short stroll from the castle lies Dunganstown Church, built on the site of an early Knights Templar foundation granted by Reginald Palmer in the late 12th century. The church’s stained‑glass windows – The Parable of the Good Samaritan (O’Connor, 1872) and Christ Blessing Children (Catherine O’Brien) – were commissioned by the Hoey family. The Hoey family vault is situated in the adjoining graveyard, and the date “1740” over the door marks the construction of the present tower.
St Kevin’s Lane and Folklore
St Kevin’s Lane, once envisaged as the main street of a planted town, still winds through the landscape. Local folklore tells of a drunken doctor who drowned in a puddle along the lane, his ghost said to appear at night. The lane connects to the “Doctor’s Avenue” and adds a layer of mythic intrigue to the walk.
Hodgins Nursery and Rare Hollies
In the 18th and early 19th centuries, Edward Hodgins operated a 16‑acre nursery on the estate, supplying rare conifers and exotic species to the National Botanic Gardens, Trinity College Dublin, and even Kew Gardens. Hodgins pioneered new holly hybrids, including the internationally recognised Dunganstown Holly (Ilex xaltralarensis ‘Hodginsi’). A plaque near the old nursery site commemorates his contribution to Irish horticulture.
The Old Forge
The old forge, dating from the 1600s and operating until 1997, remains a tangible reminder of the area’s craft heritage. Visitors can still see the stone rim used for shaping cart wheels, a cooling trough for horseshoes, and the bellows that once powered the furnace. A boundary marker on the forge wall delineates the historic townlands of Dunganstown and Ballyflanigan.
Heritage Trail Experience
The Dunganstown Heritage Trail (Pure Mile Competition 2014) strings together seven interpretive stops, each illustrated by photographs and sketches created by pupils of Brittas Bay National School. Trail guides and maps are available in local shops in Arklow and at the Brittas Bay visitor centre. Walking the trail provides a self‑guided narrative that weaves together the castle’s architecture, the ancient trees, the church, and the folklore of the lanes.
Practical Information
Dunganstown Castle is private property and not open to the public; visitors should respect the boundary walls and avoid trespassing. The heritage trail, however, follows public rights‑of‑way and offers several designated viewing points from the roadside and footpaths.
- Parking: free public car parks are available in the town of Arklow and at the Brittas Bay visitor centre, both a short walk from the trail’s start.
- Access: the trail is free of charge and can be undertaken year‑round. The footpaths are unpaved and may be uneven, especially near the old forge and the yew walk; they are not fully wheelchair‑accessible.
- Maps & Guides: detailed maps are downloadable from the Wicklow Heritage Trail website and printed copies are sold in Arklow shops.
- Best time to visit: early morning or late afternoon provides the soft light favoured by photographers and makes the tower’s ivy‑clad walls stand out against the sky.
Nearby Attractions
While exploring the trail, consider a short detour to the Arklow Maritime Museum for insight into the town’s seafaring past, or head to Brittas Bay for a coastal walk and beach.
Access & Safety
The footpaths are unpaved and may be uneven in places, particularly near the old forge and the yew walk. Visitors with limited mobility may find the terrain challenging; there are no dedicated accessibility facilities on site.
