Ashtown Castle, located in the Phoenix Park, Dublin, Ireland, is a restored 17th-century tower house nestled within the grounds of the Áras an Uachtaráin estate, the official residence of the President of Ireland. Originally built around 1640 by the Eustace family, it was later incorporated into the 18th-century Ashtown Lodge, which served as the Under Secretary’s residence. Rediscovered in 1978 during the lodge’s demolition, the castle was meticulously restored by the Office of Public Works (OPW) and opened to the public in 1998 as part of the Phoenix Park Visitor Centre. A rare example of a tower house within Dublin city, Ashtown Castle offers a glimpse into Ireland’s medieval and early modern history, set against the 1,750-acre urban oasis of Phoenix Park.
Origins and Eustace Family (13th–17th Centuries)
Ashtown Castle’s
history begins with the Eustace family, Anglo-Norman settlers who
arrived in Ireland during the 12th-century Norman invasion. Granted
lands in County Kildare and Dublin, they became prominent in the Pale,
the English-controlled region around Dublin. By the 13th century, the
Eustaces held Ashtown, a manor named possibly from the Irish Baile an
Ásaigh (“town of the ash trees”) or an Anglo-Norman family name. The
area, now part of Phoenix Park, was rural, supporting agriculture and
small settlements.
The castle itself was constructed around 1640
by Sir John Eustace, during a period of relative stability before the
Irish Confederate Wars (1641–1653). Tower houses, common in Ireland from
the 15th to 17th centuries, were fortified residences for gentry
families, combining defense with domesticity. Ashtown Castle likely
served as the Eustace family’s primary residence in Dublin,
complementing their larger estates in Kildare, such as Castlemartin. Its
strategic location near Dublin city and the River Liffey made it a
valuable outpost within the Pale.
The 1640s brought upheaval. The
1641 Rebellion, sparked by Catholic landowners against English rule,
involved the Eustaces, who were Catholic and aligned with the
Confederate cause. Sir John Eustace’s involvement led to the family’s
lands, including Ashtown, being confiscated by the Cromwellian regime in
the 1650s. The castle was likely damaged or abandoned during this
period, as the Eustaces were transplanted to Connacht under the
Cromwellian land settlements.
Post-Restoration and Ashtown Lodge
(1660–1800)
After the Restoration of Charles II in 1660, some Eustace
lands were returned, but Ashtown’s ownership became fragmented. By the
late 17th century, the manor passed to the Crown, becoming part of the
Phoenix Park estate, established in 1662 as a royal deer park by James
Butler, Duke of Ormond, and Lord Lieutenant of Ireland. The park,
enclosing 1,750 acres, was named after Phoenix House, a nearby
residence, possibly derived from the Irish Fionn Uisce (“clear water”).
In the 1780s, Ashtown Castle was incorporated into a new Georgian
residence, Ashtown Lodge, built to house the Under Secretary for
Ireland, a key administrative official. The tower house was encased
within the lodge’s structure, with its upper floors dismantled and walls
hidden behind Georgian brickwork. This adaptation preserved the castle’s
core but obscured its medieval character, as the lodge’s classical
design—featuring sash windows and stucco interiors—dominated. The lodge
served as a residence for figures like Thomas Conolly, Under Secretary
from 1787, and later park officials, including rangers and
superintendents.
19th–20th Centuries: Decline and Rediscovery
Throughout the 19th century, Ashtown Lodge remained a functional
residence within Phoenix Park, which evolved into a public park and home
to key institutions like the Viceregal Lodge (now Áras an Uachtaráin).
The lodge housed park staff, including the Chief Ranger, and was
maintained by the Commissioners of Woods and Forests. By the early 20th
century, its condition deteriorated, exacerbated by Ireland’s political
upheavals, including the War of Independence (1919–1921) and Civil War
(1922–1923).
In 1922, with the establishment of the Irish Free
State, Phoenix Park became a symbol of national identity, and Áras an
Uachtaráin was designated the Governor-General’s residence, later the
President’s. Ashtown Lodge, overshadowed by grander park buildings, fell
into disrepair. By the 1970s, it was deemed unsafe, with leaking roofs
and crumbling interiors. In 1978, during preparations to demolish the
lodge, workers uncovered the medieval tower house within, sparking
interest from historians and the OPW.
Restoration and Modern Era
(1978–Present)
The OPW halted demolition and launched a restoration
project, completed between 1989 and 1998, to preserve Ashtown Castle.
The Georgian lodge was carefully dismantled, revealing the tower house’s
intact lower floors. The upper floors, lost in the 18th-century
adaptation, were reconstructed using traditional materials and
techniques, guided by archaeological evidence and comparisons with other
Dublin tower houses, like Drimnagh Castle. The restoration cost
approximately £500,000 (equivalent to €1.2 million in 2025), funded by
the OPW and EU heritage grants.
In 1998, Ashtown Castle opened as
the centerpiece of the Phoenix Park Visitor Centre, alongside a new
interpretive facility and café. Its proximity to Áras an Uachtaráin,
just 200 meters away, places it within a high-security zone, but public
access is facilitated through guided tours. The castle’s restoration
earned praise for preserving a rare urban tower house, contributing to
Dublin’s medieval heritage narrative. In 2024, the OPW introduced
interactive exhibits, including virtual reality reconstructions of
17th-century Ashtown, enhancing visitor engagement.
Ashtown Castle is a four-storey tower house, typical of Irish
gentry residences from the 15th to 17th centuries, but notable for
its urban setting within Dublin. Measuring approximately 10 meters
by 8 meters, with walls up to 1.5 meters thick, it combines
defensive features with domestic comfort, reflecting the Eustace
family’s status.
Exterior Features
Structure: The castle
is rectangular, built from local limestone with a battered (sloping)
base for stability. Its restored hipped roof, covered in slate,
replaces the original flat roof or battlements.
Entrance: The
main entrance, on the ground floor, is a pointed-arch doorway with a
defensive yett (iron gate), reconstructed based on archaeological
findings. A murder hole above the entrance allowed defenders to
target intruders.
Windows: Narrow slit windows on the lower
floors, designed for defense, contrast with wider, mullioned windows
on the upper floors, added for light and comfort. The restored
windows use leaded glass, mimicking 17th-century designs.
Bartizan: A single overhanging turret on the southeast corner,
restored in 1989, provides a defensive vantage and adds to the
castle’s picturesque silhouette.
Interior Layout
Ground
Floor: A vaulted chamber, used for storage or stables, with low
ceilings and minimal light. A spiral stair in the northwest corner
connects all floors.
First Floor: The main living area, featuring
a large fireplace and wider windows. This space likely served as the
hall for family gatherings and administration.
Second Floor:
Private chambers, with a smaller fireplace and latrine (garderobe)
chute, indicating the lord’s quarters.
Third Floor: Additional
sleeping or guest rooms, with access to the wall walk (now closed
for safety). The restored floor includes oak beams, replicating
17th-century carpentry.
Defensive Features: Loopholes in the
stairwell and upper floors allowed for internal defense, while the
thick walls resisted artillery, a concern during the 1640s
conflicts.
Restoration Details
The 1989–1998 restoration
rebuilt the upper two floors, lost in the 18th century, using
limestone sourced from Dublin quarries to match the original. The
OPW consulted historical records and nearby tower houses, like
Rathfarnham Castle, to ensure accuracy. The interior is sparsely
furnished, with informational panels and artifacts (e.g.,
17th-century pottery) to evoke the Eustace era. The castle’s
integration into the Visitor Centre, with modern roofing and climate
control, protects it from Dublin’s damp climate.
Surrounding
Context
Ashtown Castle stands within a walled garden, originally
part of Ashtown Lodge’s grounds, now landscaped with native plants.
The Phoenix Park’s open parkland, with deer herds and historic
monuments, enhances the castle’s setting, though its proximity to
Áras an Uachtaráin restricts photography and drone use.
Ashtown Castle is a rare surviving example of a 17th-century tower
house within Dublin, offering insight into the Anglo-Norman gentry’s
lifestyle and the Pale’s fortified landscape. Its construction by the
Eustace family reflects the tensions of the late Gaelic and early modern
periods, as Catholic landowners navigated English rule. The castle’s
role in the 1641 Rebellion and Cromwellian confiscations underscores its
entanglement in Ireland’s turbulent 17th century, a time of shifting
power dynamics.
Its rediscovery in 1978 and restoration highlight
Ireland’s growing commitment to preserving medieval heritage, especially
within urban contexts. Unlike rural tower houses, Ashtown’s location in
Phoenix Park—a national symbol and one of Europe’s largest enclosed
parks—amplifies its significance, linking it to Dublin’s civic identity.
The castle’s story, from a hidden relic within a Georgian lodge to a
public heritage site, mirrors Ireland’s reclamation of its past
post-independence.
Culturally, Ashtown Castle serves as an
educational hub, with the Visitor Centre’s exhibits on Phoenix Park’s
history, from its 1662 founding to its role in events like the 1979
Papal Mass. The castle’s modest scale, compared to grander sites like
Dublin Castle, offers a personal perspective on medieval life,
resonating with visitors seeking authentic history. Local folklore,
though minimal, includes tales of a “grey lady” haunting the site,
likely a modern invention to enhance tourism.

Ashtown Castle’s urban setting and small size present unique
preservation challenges. The 1989–1998 restoration addressed structural
issues, including damp penetration from Dublin’s wet climate, with
modern drainage and a waterproof roof membrane. Annual maintenance,
costing €50,000, focuses on stonework and window conservation, funded by
the OPW.
High visitor numbers (approximately 30,000 annually)
strain the castle’s narrow interiors, prompting timed tours and capacity
limits. The park’s biodiversity, including deer and bats, requires
balancing tourism with ecological protection, with restricted lawn
access near the castle. Climate change, with increased rainfall,
threatens the limestone walls, mitigated by regular repointing (last
completed 2023, €20,000).
The castle’s integration into the
Visitor Centre ensures accessibility but limits expansion. The OPW’s
2023–2028 Phoenix Park plan prioritizes sustainable tourism, with
solar-powered lighting and digital ticketing introduced in 2024 to
reduce environmental impact.
