Referred to as the "mother church" by many Episcopalians ...instrumental in organizing the Episcopal Church after the Revolution from the shattered Church of England.
The baptismal font in the back of the church was sent to Philadelphia in 1697 from All Hallow's Church Barking-by-the-Tower, London. It is the font from which William Penn was baptized.
There are burial stone markers on the floor which mark the graves of early noteable men.
Study up on your history before you visit Philadelphia and you'll be rewarded with a more satisfying visit. It's great to walk the same streets as George Washington, Ben Franklin, John Penn, Robert Morris and many other icons of American history.
Here's a shot of the interior of Christ Church, where all of the above mentioned men worshipped at one time or the other.
Favorite thing: CHRIST CHURCH BURIAL GROUND: Burial place of Benjamin Franklin & other notables. The site is just opposite the U.S. Mint.
