The Divinity School gained its own visual identity when the Kilgo portico was added in 1965. Originally these two side-by-side classroom buildings had identical arched entrances. The addition of an extended portico with a distinctive stone carving identifying the Divinity School brought that building in line with others in the main quadrangle with prominent identifying stone carvings. A considerable addition was completed at the same time but it was not visible from the Chapel Court.
