The Moravian Church, an outgrowth of a reform movement in 15th century Bohemia and Moravia, is one of the oldest Protestant bodies in the world. Wisconsin was inviting to Moravian refugees, and by 1890, there were 1,477 Moravians in Wisconsin, with Jefferson County having the highest concentration. London Moravian congregation began as a small group of worshippers in 1889 who met in homes, school houses, and even in a Methodist church. The first worship service in London was held March 28, 1889.  The date of organization is October 6, 1889.  Services were held in homes and then a schoolhouse.

The early years were a struggle – during 1893 and 1894 the church nearly folded. On Nov. 18, 1894 the church building was dedicated on land bought from Robert Cayhey. Services were originally held in German and into the 1930’s German services were still held for special occasions. Today, with a congregation of about 90 members, London Moravian is one of fewer than 20 Moravian churches in Wisconsin, and has the distinction of being the only Moravian church on the Koshkonong Prairie.
