Saint Peter's Church/Our Lady of the Rosary is a Catholic church in the Financial District of Manhattan, New York City.

Shortly before, and during the Revolution, Father Ferdinand Steinmeyer, a German Jesuit missionary from Philadelphia, would periodically visit the few scattered Catholics in New York City.

[6] The merchant and recent New York arrival Dominick Lynch was one of the chief fundraisers for the new church, donating his own money as well as raising funds from his native Galway.

[7] A gift of 1,000 silver pieces from King Charles III of Spain through the prominent figures of the Spanish Diego de Gardoqui and D. Francisco de Murillo i Martinez, Count of El Ojuelo, topped off donations to start the construction of the church.

[8] Catholics constructing the original church initially tried to locate it on Broad Street, then in the heart of New York City.

Mexican artist Jose Vallejo painted an icon of the Crucifixion[9] and Nunez de Haro, archbishop of Mexico City, gave it to St. Peter parish in 1789; it hung above the main altar.

[10] Father William O'Brien, the first pastor, is remembered for his tireless service to the citizens of New York during the yellow fever epidemics of 1795 and 1798.

Edward Frederick Sorin, founder of the University of Notre Dame, celebrated Mass upon his arrival in America in 1842.

[13]The next day, a portion of an airplane's landing gear struck and damaged the roof of the St. Peter's Church building during the September 11 attacks.

Mychal (the first publicly identified casualty of the attacks), surviving firemen brought him from the towers site to St. Peter's and laid his body before the altar.

"Stuff was piled six feet high all over the pews—-bandages, gas masks, boots, hoses and cans of food for the workers and the volunteers, many of whom were sleeping in the church on bedrolls.

[19] St. Peter's houses a pipe organ built in 1927 by the George Kilgen & Sons company of St. Louis, Missouri.

In 2011, Meloni & Farrier Organbuilders completed a restoration, installing solid state combination action and relocating the console to its present location in the rear balcony.
