Trinity Episcopal Church carries with it many memories and associations dating back to pre-Civil War days. It was the first non-Catholic church in Natchitoches and the third Episcopal church in Louisiana.
The building itself is of Gothic-Norman architecture; the exterior walls, of masonry, vary in thickness from 22 to 28 inches. The interior is spanned by large laminated wood arches which resemble a wagon vault. All beams are tied directly into the brickwork. The wood flooring is of handcut timber. A sturdy, buttressed bell tower gives added dignity to the main structure. The bell, said to be of one-third silver, was cast especially for this church at the Troy Bell Foundry of Troy, New York.
In 1917, the 60th anniversary of the present chuch building was celebrated with a special sevice on June 3. The service included a history of the congregation prepared by the then rector, The Reverend J. Orson Miller. A newspaper article including the "historic sermon" was also pasted into the parish register. It has been transcribed here.
The parish hall and classroom wing was added in 1962. It was designed by architect A. Hays Town to blend well with the architecture of the original building. The general contract for the project was Marbry Jones, a member of the parish, and the brother of the then rector, Julian Jones.
In 2003, the front porch was extended and a ramp was added to provide easier access to the church. The architect for the project was George W. Minturn, a member of the parish, who remained mindful of the need to remain true to the style of the original building, while accommodating the needs of all who wish to worship here.
