In 1866 Bishop Claude M. Dubuis of Galveston sent a young French immigrant, Emil L. J. R. Fleury, to organize a congregation and build a church to serve Boerne and the outlying towns and army posts. This stone structure was completed in 1867. Features include an entry portico with shingled gable end, a small belfry, and segmental-arch windows. Fleury, who left Boerne in 1869, returned in 1923 to help lay the cornerstone for a new sanctuary. Recorded Texas Historic Landmark - 1987
