The Gethsemane Holiness Church is in the Georgian style named after four British kings, George I, George II, George III, and George IV. They held office from 1714 to 1830. The Georgian style in this country is considered Georgian Revival architecture or Colonial Revival. Wikipedia tells:
The Georgian style is highly variable, but marked by symmetry and proportion based on the classical architecture of Greece and Rome, as revived in Renaissance architecture. Ornament is also normally in the classical tradition, but typically restrained, and sometimes almost completely absent on the exterior. . . . Georgian architecture is characterized by its proportion and balance; simple mathematical ratios were used to determine the height of a window in relation to its width or the shape of a room as a double cube. Regularity, as with ashlar (uniformly cut) stonework, was strongly approved, imbuing symmetry and adherence to classical rules. . . .
