The former St. Paul's Anglican Church is a typical example of early ecclesiastical architecture in Upper Canada. Built of fieldstone and later parged with stucco, the layout of this early structure was a simple rectilinear plan with the front gable end punctuated by the central tower and steeple. Balanced by flanking gothic windows, the front double door entrance has a stained-glass gothic transom and a smaller gothic window centred above.

One of the oldest in existence in Canada, the church was built in 1811 by the Baptist congregation of Abel Stevens, founder of Delta. In 1827, the church was purchased by the Anglican Church of Canada. Until 1864, both the Baptist and Anglican congregations shared the church and used it as a place of worship. Between 1843 and 1862, the Methodist congregation also used the church as a place of worship. In 1864, the Baptist congregation sold their shares in the church at which point the Anglican congregation became the sole users of the church and named it St. Paul's Anglican Church.
