In
1983, Parks Canada designated the church a National Historic site.
A Historic Sites and Monuments Board of Canada plaque was unveiled,
describing the churchs historic significance. After the fire
of 1994, the plaque was revised to reflect the fire and subsequent
restoration. The plaque currently on display reads as follows:
Begun in 1800, this distinguished round church
illustrates a refined but rare aspect of the Palladian architectural
style. It is the only known Canadian Church of this period to
adopt the circular form recommended by the Renaissance architect
Palladio. The unusual form is attributed to Edward, Duke of Kent
and the detailed plans to master shipwright William Hughes. Modifications
carried out during the 19th century have not altered its original
appearance. Restored after a devastating fire in 1994, the church
retains its harmonious classical form.
