The Columbus Cathedral is a Roman Catholic Church in the Grand Theft Auto IV and Grand Theft Auto: Chinatown Wars renditions of Liberty City, located in Hatton Gardens, Algonquin on Columbus Ave between Lorimar Street and Manganese Street. It is based off of St. Patrick's Cathedral in New York City.
The building is not prominent in any missions. It is simply there as a church based off of St. Patricks Cathedral. In the complex of the church, however, there is a garden, where there are usually people walking around the complex and people sitting on the benches.
The stained glass windows on the Columbus Cathedral have a design exactly the same as the Triforce in the legend of zelda games
