Smarmore Castle Drug & Alcohol Rehab
A Historic Setting for Recovery
Smarmore Castle is a private addiction treatment clinic set in a tranquil 15-acre estate in County Louth. A fine period house steeped in history and charm, it incorporates a medieval tower, dating back to 1320. Today, this peaceful, historic setting has been thoughtfully restored to provide a safe and welcoming environment where people can focus on their recovery with dignity and privacy.
The natural beauty and calm of the surroundings of the Irish countryside play an important role in the healing process. Patients often tell us that being away from the pressures and triggers of everyday life helped them find the space to reflect, grow, and begin to rebuild their lives.
Located just 45 minutes north of Dublin and 1.5 hours south of Belfast, Smarmore Castle offers expert care in a setting that feels truly restorative.
Our Vision
Every person with an addiction who comes through the doors of Smarmore Castle has the chance to start their recovery journey and turn their lives around. We help change the lives of not just our residents, but their loved ones – wives, husbands, parents, children, friends.
At Smarmore Castle, our vision of ‘recovery’ goes beyond helping patients when they are here; we want to help them forge their very best life with the therapeutic tools they need to stay abstinent and live fulfilled lives in recovery. This is as true today as it was in 1983 when our founders, Peter and Dr Margaret McCann founded their first addiction treatment centre in the UK.
