[1] It is located on what was once termed the "Slí Mhór" (Irish: Great Way), a key route that ran westwards across Ireland from Dublin.

[2] After a period of decline, and later of refurbishment, St. Catherine's was re-consecrated and has been the place of worship for the Anglican "CORE" church (City Outreach for Renewal and Evangelism) since then.

[4] The parish of St. Catherine appears to have been the only viable one in the area at that time — Roman Catholics eventually got the use of a chapel in Dirty Lane (now Bridgefoot Street) towards the end of the 17th century.

[5] The building that stands now was originally built between 1760 and 1769 to the designs of the architect John Smyth[2] (who was also responsible for the interior of St Werburgh's Church, among other works in Dublin at the time).

[2] Worship was transferred to its former chapel of ease the Church of St. Victor, which was renamed St. Catherine and James Church, Donore Ave. St. Catherine's was transferred for a number of years to Dublin Corporation, and was used for exhibitions and concerts - hosting artists such as Christy Moore and The Chieftains.

An Anglican group (City Outreach for Renewal and Evangelism - CORE) took on the refurbishment of the church in 1993, and the interior was largely restored by the end of 1998.
