The effusive academic detail of this society church contrasts markedly with Richardson's Emmanuel Episcopal Church (AL70) a block away. Calvary, whose Gothic Revival facade is marked by the enlivening contrast between the two differently sized facade towers, was almost a private devotional project for the four main families that backed it. So expensive was land in 1892 when Allegheny City was at its fashionable height that one-quarter of the budget is said to have been spent just for the site. Construction of the church cost another quarter of the budget, interior furnishings another quarter, and the last quarter went (by private subscription) into three of Louis Comfort Tiffany's best windows: the Apocalypse, Resurrection, and Ascension.
