The Trinity Episcopal Church congregation has been a mainstay in the Kirksville area since 1870, when first established as an outreach mission.[3] The first church building, a wooden structure, was constructed in 1870 on the site of the current church and served the congregation until 1916. A fire in 1907 caused major damage and despite repairs it was apparent the original building would not remain usable.[3] In October, 1915 the congregation petitioned the Episcopal Diocese for assistance and were successful in reaching an agreement on financing.
Well-known local architect and congregation member, Irwin Dunbar was selected to design the new building and during 1916 the former wooden structure was razed to clear path for the new church.[3] Construction was begun in the spring of 1917 with the local firm of Eggert & Russel chosen for the task. The cornerstone was laid on May 14, 1917, and building progressed rapidly with the consecration of the new church on November 7, 1917. Total completion cost for the project was $11,555, the Diocese contributing $5,500.[3][4]
The building was constructed in a bungalow/craftsman, Gothic Revival style with the finished dimensions approximately 37 feet by 67 feet.[2] With the 1907 fire still fresh in their minds, the congregation chose the slightly higher cost of a brick structure as opposed to wood. The building is somewhat asymmetrical in nature and sits atop a raised basement.[1] When designing the interior, Irwin Dunbar chose some features that reflected not only a blend of Craftsman and Gothic Revival styles, but his own background as an engineer. Most notable of those are the open beam ceiling in the nave, constructed of black walnut.[2] These trusses provided support for the heavy English tile roof, yet kept the worship area free of cumbersome columns. Black walnut was used extensively throughout the interior for trim, window frames, and other ancillary features.[3]
