The first Methodist sermon in Watertown was preached in 1794 and the town’s first Methodist Class was formed in 1800. As described in the History of Ancient Westbury and Present Watertown from its Settlement to 1907 (1907):
On February 21, 1853, a meeting was held in the office of Dr. Catlin to discuss the feasibility of establishing Methodist worship at Watertown Centre, and it was voted desirable to have preaching here the following conference year. Much difficulty was experienced in securing a suitable place for these meetings, and the committee accepted the invitation of General Merritt Heminway to use the ball-room in his hotel during the summer. Rev. Larmon Abbot preached the first sermon here May 29, 1853. There being no facilities for heating the ball-room, during the winter the Congregational chapel was rented for the use of the Society. In October, 1854, the basement of the new Church was ready for use, and the edifice was dedicated December 13, 1854.
. . . In 1897, the membership of the Church having greatly increased, it became necessary to build a larger edifice. $9,500 was subscribed, largely through the influence and generosity of Augustus N. Woolson. He also purchased the old Church for $1,000 and removed it. A call for more money for carpets, organ, etc., was met by the same generous giver. And not only in his Church was Mr. Woolson’s influence felt. He represented the town in Legislature, and was sent by the unanimous vote of his townsmen as delegate to the Constitutional Convention. Many homes in the town were made happier by his benevolence. It has been said that for a quarter of a century before his death there was no movement looking toward the improvement of Watertown in which he had not a prominent, if not a leading part. He was an honest and successful business man, a model citizen, a philanthropist and a sincere Christian.
Completed in 1898, the church (305 Main Street) was designed by George W. Kramer, whose book The What, How and Why of Church Building was published in 1897. Kramer also designed the Methodist Church in Derby, the Asbury United Methodist Church in Bristol (1900) and St. Paul’s Methodist Church in Hartford (1900).
