St. Monica Roman Catholic Church, ca. 1905. Founded in 1879, St. Monica's was the fourth Catholic parish established on the Upper East Side. While the first services were conducted in a small second-story store space, the church moved into its first new church building in 1883. In 1906 the firm of Schickel & Ditmars, well known for their Catholic church architecture completed the current church. The Gothic Revival building opened for services on Thanksgiving Day.

The Church of St. Monica was founded in 1879 by the same pastor that had founded St. Joseph’s. St. Monica’s grew out of humble beginnings, with the mission to serve the expanding Irish Catholic population of the neighborhood. The current building at 413 East 79th Street, shown here at the year of its completion, 1905, was designed in a Gothic Revival style by the firm Schickel & Ditmars. Its facade on East 79th Street remains nearly unchanged since construction.
