As described in History of the town of Litchfield, Connecticut (1845), by George C. Woodruff:
The members of the Church of England in this town, associated together for public worship about the year 1746, and it appears from their records that the Episcopal Society “was organized according to law, on the 26th of October, A, D. 1784.” Their first Church was erected nearly opposite the carriage manufactory of Mr. William Lord, about one mile westerly from the Court House. Their Church in the village was completed in the year 1812.
As further related in Historic Litchfield, 1721-1907 (1907), by Alice T. Bulkeley:
St. Michael’s Episcopal Church was dedicated in 1851 and is the third edifice, the first being built in 1749 about a mile west of the courthouse. The present church had a spire above the tower which was blown down in a storm a few years ago.
The current church building was erected in 1919-1921. In The Litchfield Book of Days (1900) is the following story about the earliest of these four church buildings:
When General Washington passed through Litchfield in the Revolutionary War, the soldiers, to evince their attachment to him, threw a shower of stones at the windows of the Episcopal Church. He reproved them, saying: “I am a Churchman, and wish not to see the church dishonored and desolated in this manner.”
