The congregation of Calvary Episcopal Church was begun by the Episcopal missionary Bishop George Maxwell Randall, who later would establish the Colorado School of Mines. This chapel, built upon land donated by William A.H. Loveland, was constructed in 1867-68, and has been in use by the congregation ever since. It was designed by a member of the original church vestry, and is the earliest known work constructed by prominent regional builder John H. Parsons.
