St. Paul's Cathedral is a masterpiece of Gothic Revival architecture in the United States.  Completed in 1851 by the architect Richard Upjohn who was best known for designing Trinity Church (1849) on Wall Street in New York City.  Upjohn, an English immigrant, brought his appreciation for picturesque Gothic churches in the English countryside to bear on his design for St. Paul's in Buffalo.  He created a highly unusual plan for the sloping, triangular piece of property that was donated to the Episcopal congregation in the first half of the nineteenth century.  Most Gothic churches are built in the "cruciform," or cross plan, with a long nave down the center and two transepts which cut across thus forming a footprint in the shape of a Christian "cross."  St. Paul's has an irregular plan which from the exterior appears like a series of separate edifices linked together.  The interior is stunning with its hammer beam roof and clerestory of twelve windows featuring the twelve apostles.  Gold leaf adorns triumphant angels high above.  The church features significant stained glass windows, including one Tiffany window in the chapel on the northeast side of the church.  The church is open most days and can be entered via the stairs on Pearl Street.  Located just across the street from the Guaranty/Prudential Building at 128 Pearl Street, Buffalo, NY 14202.
