St Peter's College, University of Oxford (formerly St Peter's Hall), is on the west side of the street. The college occupies the site of two of the University's oldest Inns (medieval hostels), Bishop Trellick's, later New Inn Hall (after which the street is named), and Rose Hall, both founded in the 13th century. The college chapel was built in 1874 on New Inn Hall Street, originally as the parish Church of St Peter-le-Bailey. Two previous church buildings of the same name were previously at the southern end of the street, near Bonn Square, where the graveyard used to be. The church was so named because of its proximity to Oxford Castle.
