Old St. Mary’s Roman Catholic Church

Founded in 1763, Old St. Mary’s Roman Catholic Church was one of the nation's earliest Catholic churches and the first Roman Catholic cathedral in Pa. At a time of anti-Catholic sentiment in Colonial America, it symbolized the religious tolerance of Pa. that was later adopted in the US Constitution. The Continental Congress attended services there several times as a sign of respect for the Catholic countries of France and Spain, America's allies during the Revolutionary War.
