Apart from these vestries, which retain the established style and proportions, the church externally remains "fine Georgian" much as Greenway conceived it. Relying on the "virtues of simplicity and proportion to achieve his end", Greenway maintained the classical tradition, unaffected by the Revivalist styles that were being promoted in London at the time he arrived in the colony. He planned the church to align with his earlier Hyde Park Barracks, constructed in 1817–19. The two buildings have similar proportions, pilasters and gables and together constitute an important example of town-planning. Before the advent of high-rise buildings, the 46-metre (150 ft) spire used to "serve as a guide for mariners coming up...
