Just in case anyone wishes to actually GO there, I should mention that St. Francis Xavier church in Manhattan is 1 block further north than I placed it above. The actual address is... 30 West 16th Street, between 5th and 6th Avenues.

While you're in Manhattan, you should also visit the FIRST St. Patrick's Cathedral at 263 Mulberry Street @ Prince Street. Hibernian Hall, i.e. the ORIGINAL Hibernian Hall where Michael Corcoran worked as a bartender and the 69th Regiment gathered, is across the street.

All the best,
Dan
