St. Michan's Church, Dublin

Architecture

Built on the site of an early Norse chapel from 1095, St. Michan's is the only parish church on the north side of the Liffey surviving from a Viking foundation.

The current structure dates largely from a reconstruction undertaken under William Robinson in 1686, and a former almshouse (later used as church offices) was built on the grounds c. 1720. The church was renovated c. 1825, and a two-storey vestry added on the northern side of the church.

While the exterior of the church may be modest, the interior has some fine woodwork, and an organ (dated 1724) on which Handel is said to have composed his Messiah.

Interments

The vaults of St. Michan's uniquely contain many mummified remains. The walls in the vaults contain limestone, which has kept the air dry, creating ideal conditions for preservation. The remains preserved in the vaults have included the 400-year-old body of a nun, a six-and-a-half-foot man popularly believed to have been a crusader, a body with its feet and right hand severed, and the Sheares brothers—Henry and John—who took part in the 1798 rebellion. The various holders of the title Earl of Leitrim were also interred here.

Several grave markers, within the adjoining cemetery, date to the mid-17th century.

Vandalism and arson incidents

St. Michan's crypts have been repeatedly damaged by vandalism, including two arson attacks.

In July 1996, vandals broke into one of the church's five burial vaults, removed bodies from their coffins and started a fire using rags and paraffin. The vault was destroyed. Firefighters extinguished the blaze, although the water used also damaged the remains. The disturbed bodies were reinterred during a church service. The four undamaged vaults remained open to visitors, while the destroyed vault was permanently closed. Recalling the incident 23 years later, in 2019, David Pierpoint, Archdeacon of Dublin and rector of St. Michan's Church, said the vandals had dragged bodies onto the ground and appeared to be playing football with their heads.

Over the weekend of 23 and 24 February 2019, an intruder again entered the crypt. The mummy known as "the Crusader" was decapitated and its head stolen along with another skull. The remains of the nun were damaged, while other bodies, coffins and the family vault of mathematician William Rowan Hamilton were also disturbed. The stolen remains were recovered by Gardaí in early March 2019. Brian Bridgeman pleaded guilty to burglary and five counts of criminal damage, including two counts of damaging a dead body, and was sentenced to 28 months' imprisonment in July 2019. Following restoration work and improved security, the crypt reopened to visitors on 9 July 2019.

Nearly five years later, on 11 June 2024, an intruder deliberately set fire to the crypt. The fire, and the water used to prevent it spreading to the wider church, left five mummified remains, including the Crusader, destroyed or damaged beyond repair. In February 2025, Cristian Topiter was sentenced to six years' imprisonment after pleading guilty to arson.

Before the 2024 fire, the crypt received approximately 30,000 visitors each year. As of March 2025, public access to the crypt had been suspended for about nine months while conservation work continued. Pierpoint said the closure was expected to cost between €75,000 and €100,000 in lost income.
