The last marriage service was held in the Holy Trinity Church - the marriage of William J.J. Ballard to Jane H. Dix.

This was the last recorded in Trinity's marriage certificate stubs (no. 427). This was also confirmed in a small evening post article on the same day.

A 'service of praise' is recorded on 14 March, which may in fact have been Holy Trinity's last official service. On 28 March the final service recorded in Holy Trinity's service register was taken by Terence Kelshaw.  There was a morning and an evening service on this day - Mothering Sunday, though the service may have been held at Easton Family Centre due to the Church's closure.

With the final hymn ringing around the almost vacant pews of Holy Trinity, a praise song and a funeral rite calling time on a church once described as 'the Cathedral of the East'.

The music that followed could not have been more different...

The 1961 Bristol census shows that the population of the parish of Holy Trinity has fallen dramatically to 3,354 , from 5,182 in 1951 (allowing for changes to the parish boundaries). The Bristol Diocesan Finance Board use this as an example of a reduced need to support the Church.

A series of expensive repair works were identified during the period, including cleaning to stonework anessential repairs to roof timbers. In 1964 repairs to steelwork were carried out, but costs of upkeep quickly became too costly for the church to bear.

In 1968, a rapidly dwindling congregation and lack of money led to the church to explore avenues for redundancy.

Trinity was originally designated a Grade II Listed building in January 1959.

On 30 December 1994 the Church was re-listed by the Department of National Heritage as Grade II* - This means it is a 'particularly important building of more than special interest.'

The listing details on Historic England's website states:

Church. 1829-32. By Thomas Rickman and Hutchinson. Later work c1882 by John Bevan and 1905 by WV Gough. Bath stone ashlar with a slate-roofed nave and leaded aisles. Chancel and aisled nave. Perpendicular Gothic Revival style. Small semi-hexagonal apse with pointed windows, beneath a crenellated, gabled end with angled buttresses and a large Perpendicular E window. The N aisle is 4 bays, with segmental-headed windows between weathered buttresses, and a coped parapet ending with crocketed pinnnacles; at the W end is an arched doorway; 2-light clerestory windows. Similar S elevation. The W front has a pair of crenellated octagonal towers of openwork tracery flanking 3 Tudor-arched doorways, the largest in the middle within a label mould with chamfered reveals and quatrefoils in the spandrels; above is a large 5-light window similar to the E end, and a traceried balustrade with open merlons and a cross finial to the top of the gable. INTERIOR: all fittings have been removed and a floor inserted near the top of the nave arcade. This consists of 4-bay arcade of square piers without capitals and pointed arches, with slender stanchions between for the absent gallery. Flights of stairs lead up either side from the narthex. An early Commissioners' church, now put to community use.

The building was included in the list for protected buildings in Bristol by the Ministry for Housing and Local Government.

The Holy Trinity was built as part of a national programme of church building approved by Parliamentary commission. Funds for the programme totalling one and a half million pounds came in part from the spoils of Napoleonic War, hence these churches are variously known as Waterloo Churches (after the famous battle), Commissioners Churches and One Million Churches.

The Holy Trinity Church was built between 1829 and 1832, designed by renowned Birmingham architects Thomas Rickman and Henry Hutchinson.

The last rector to serve at Trinity, Terence Kelshaw, explains:
“Trinity was a society church. It was built by Harpur’s for their workers so in order to work at Harpur’s you had to show your seven year certificate which was a certificate directly signed to say you had attended Sunday school or church for seven years...you needed the certificate to get work. It was called a seven year certificate. That’s why there was a balcony in there for the workers children - so the children sat up in the balcony. They [Trinity and surrounding churches] were built as company gifts to their workers...”

The population of St Phillips was deemed big enough to need the new church and Holy Trinity became a parish (a division of the city served by its own church) in its own right. The church was able to seat 2,000 people, though only 1,500 were ‘free’ seats – the others near the front were paid for by keen churchgoers, meaning that they could sit ‘closer to God.’ Although Trinity was a ‘daughter’ Church to St Phillips and St James – known colloquially as "Pip and Jay" – it became the most highly esteemed in the area, owing to a combination of its position, size, level of activity and vividness of its stained glass window.

Gloria and Mervyn Evans were married in 1963.

16th February 1946 proved to be a very busy day at Holy Trinity as the Vicar, Reverend Frederick John Barff carried out five wedding ceremonies, the first of these being the marriage of Joseph William Bond to Phyllis Ruby Clout.

Joseph was a Devonian who, with the impending threat of war, had enlisted early in June 1939, serving as a Flight Sergeant in the Royal Air Force, seeing active service in Egypt and also in Italy where he was also involved helping the mass evacuation of local residents when Mount Vesuvius erupted in March 1944.
Phyllis, the daughter of Joel & Annie Clout of Winsford Street, St Philips, had met Joseph during the war in Plymouth.

Discharged from the Forces in June 1946 the couple initially lived in Bristol before moving to Portishead where they spent their married lives and raised a son and two daughters.
