 An ancient Egyptian obelisk had been erected in the square outside, but had not been quite aligned with Michelangelo's building, so Maderno compensated, in order that it should, at least, align with the Basilica's façade.The nave has huge paired pilasters, in keeping with Michelangelo's work.The size of the interior is so "stupendously large" that it is hard to get a sense of scale within the building.
