Cathedral of St. John, Providence

The Cathedral of St. John, located at 271 North Main Street, is the seat of the Episcopal Diocese of Rhode Island of The Episcopal Church. The parish was originally organized in 1722 as King's Church, a wooden structure that was renamed St John's Church in 1794. That building served Providence until 1810 when work began on what would become the Cathedral of St. John. The Episcopal Diocese of Rhode Island was formed in 1790, but it was not until 1929 that St John's Church was designated the Episcopal seat and was renamed the Cathedral of St. John.

The cornerstone for St. John's Church was laid in 1810 and the church was dedicated in 1811. The building was designed by Federal-era architect John Holden Greene, who designed many buildings in Providence. A Cathedral corporation was formed in 1909 and in 1929, the church was designated the Episcopal seat. The building was renovated in 1855, 1866, 1906, and 1967, and still retains its architectural integrity, but is in a state of deterioration and was listed on the Providence Preservation Society 10 Most Endangered Properties List in 2007, 2008 and 2010.
