The first Anglican church in Milford, named St. George’s, was built from 1769 to 1772. The church was not consecrated, but rather “set apart” and dedicated for Divine Service in 1775, because Connecticut did not yet have a Bishop. In 1849, the original wooden church was demolished and replaced by the current brownstone church, designed by Frank Wills, a prominent architect and Gothic Revival churches and author of Ancient English Ecclesiastical Architecture and its Principles, Applied to the Wants of the Church at the Present Day (1850). The church was completed in 1851 and consecrated as St. Peter’s Church. The rededication of St. Peter’s Episcopal Church in 1981 was followed by a disastrous flood in June 1982, after which the organ and parts of the church and parish hall had to be rebuilt.
