[a] a local landowner and Conservative politician who served as Member of Parliament (MP) for Cardiganshire from 1816 until shortly before he died in 1854.

[3] He lived at Nanteos and developed much of Aberystwyth in the 1820s; including Laura Place which fronts the present church.

[4] By the later 19th century, the accelerating development of Aberystwyth as a seaside resort brought calls for a larger, and more impressive church.

[6] Powell commissioned designs for the new structure from Nicholson & Son of Hereford and the present church was built between 1886-1890.

[7][b] The west vestry is all that remains of Haycock's church,[9] This fragment is a Grade II listed building.

[13] Major repairs were undertaken to the church roof in the 21st century, following storm damage from Cyclone Dirk.

[13] Thomas Lloyd, Julian Orbach and Robert Scourfield, in their Carmarthenshire and Ceredigion volume in the Pevsner Buildings of Wales series, consider it "old-fashioned", even at the time of its construction.

[19] Carved panels in a memorial chapel at the front of the church commemorate the dead of Aberystwyth from the First and Second World Wars.
