Christ Church Cathedral is the oldest building still standing on Monument Circle, dating to 1857, and one of the oldest in the whole city. It's actually the second church on this spot. This building replaced the original 1838 church. There used to be five churches on Monument Circle, but this is the only one left.

This church almost didn't survive either. It faced significant challenges as the city expanded and its parishioners moved further out. And the prime parcel was heavily sought for other, more intense uses. Even back in the 19th century, the next door Columbia Club secured an option to buy the site for expansion, but a public outcry saved the building. Today the small, English gothic church stands alone on the Circle as a reminder of an older era.

Christ Church Cathedral is an active Episcopalian church and seat of the Diocese of Indianapolis. It is well known for its music programs, including frequent organ and choral performances. Its Cathedral Choir of Men and Boys was founded in 1883 and has an international reputation, with several tours and recordings to their credit.

The church is open to the public. Of particular note are the historic stained glass windows by Tiffany that were restored in 1979.
