Why it's listed

Trinity Episcopal Church occupies a large lawn on Fall Island, in the Raquette River at Potsdam, New York. Begun in 1835 as a plain Federal-style building with Gothic lancet windows, it was later expanded and transformed into a High Victorian Gothic church of red Potsdam sandstone. A chancel was added in 1857, a chapel in 1884, and in 1886 a new front facade with a 110-foot tower and rose window, designed by Ogdensburg architect James P. Johnston. A parish hall followed in 1955. The Clarkson family, who helped found the parish and owned the sandstone quarries, paid for much of this work over a century. As the congregation moved toward more elaborate worship, the interior gained carved butternut pews, a black ash vaulted ceiling, a carved eagle lectern and seven opalescent windows from the Tiffany studios. The 1835 side walls remain, and a stone wall, cast iron urn and lamp post survive on the grounds.

Significance in brief: The church was largely created by the Clarkson family, who financed its founding and its successive additions from the 1830s to the 1930s. It shows the Victorian shift of the Episcopal Church toward more elaborate architecture and furnishings. It is built of red Potsdam sandstone from the Clarkson quarries and holds seven Tiffany windows, and it is part of a multiple property listing on Potsdam sandstone buildings.

What listing means for this property

Religious properties are listed for their architectural or historical significance, not their religious use. Listing is honorary and does not restrict the congregation's use of the building. The federal rehabilitation credit is generally unavailable unless part of the building is income-producing; some state programmes and preservation grants do cover religious buildings. Federal funding or permits trigger Section 106 review.

General information, not legal or tax advice. Rules change; confirm with your State Historic Preservation Office or a qualified adviser.
