It was situated in High Street, at the corner of Christ Church lane, immediately opposite the western end of the cathedral, where the former Synod Hall now stands.
In 1554 St. Michael's was one of three Prebends in Christ Church set up by Archbishop Browne.
[1] For a number of years, it fell into ruin, but was rebuilt in 1815, when Dr. Graves, Dean of Armagh, was Prebendary.
It was mostly demolished (except the tower) by George Edmund Street later in the 19th century during his restoration of Christ Church Cathedral.
[2] Thomas Taylour, 1st Marquess of Headfort, founder of the Bective family, who worked with William Petty in compiling the Down Survey of Ireland, was interred here in 1682.
