Bryn Athyn Cathedral is the episcopal seat of The General Church of the New Jerusalem, a denomination of Swedenborgianism. The main building is of the Early Gothic style, while the adjoining structures are of a transitional period reflective of a combination of both Gothic and Norman styles. The exterior appearance of the Cathedral itself is reminiscent of Gloucester Cathedral in England.
The Cathedral is located in Bryn Athyn, Montgomery County, Pennsylvania just outside the city of Philadelphia. Bryn Athyn is also the site of the General Church affiliated Academy of the New Church, which publishes Swedenborgian literature, and is the parent organization of a high school, a four-year college (Bryn Athyn College of the New Church), a theological school, and the Emanuel Swedenborg Library.
