Trinity is one of the seven original parishes when the Episcopal Diocese of Florida was received into union with the General Convention in 1838.

Bishop Nathaniel Bowen of South Carolina formally consecrated Trinity Church on June 5, 1834.

The next 50 years saw a slow recovery by St. Augustine and Trinity, with continued work by a committed laity that raised funds to keep the church going through a succession of Rectors.

Work began in early 1902 and on January 17, 1903, the first services were held in the “new” church, a cruciform structure, neo-Gothic in appearance that seated 300 parishioners.

The 20th century brought profound changes to St. Augustine including a substantial increase in population and a steady rise in winter visitors – many of whom chose Trinity as their church.

Architecturally, the new facilities and cloistered walkways complemented and continued the neo-gothic features of the historic church building.

Ten windows, including the Triptych above the altar were made by Franz Mayer & Co. of Munich, Germany.

Two windows were given as general thank offerings, twenty six are memorials to loved ones: wives, husbands, sons, other family members and rectors.

The four Evangelists - Matthew, Mark, Luke and John - accent the original entrance on King Street.

Symbols of the Christian faith are found in all the windows; the dove, wheat and grapes, lilies and passion flowers, crosses, bibles, staffs and scripture citations from the Old and New Testaments.

Each of the twenty eight windows is different, but together they form a mosaic of color and sunlit beauty that accentuate the dignity and serenity of Trinity Episcopal Church.

Between 1991 and 1992, Advent Glass Works conducted an inspection and appraisal, then performed total restoration of twenty-nine windows in the church.

A three manual, 22-rank Austin Organ, model Opus 504, was placed in the church during 1914 in memory of Junius T. Smith by his widow, Laura.

He created a renovation plan which included a thorough cleaning, console restoration and replacement or repair of a few groups of pipes.

Helen Stephens died in 2001, and her family honored her memory in November 2003 by presenting the church with an automated carillon that will play a song on the quarter-hour during the day.
