The medieval church was repaired in 1623, only to be destroyed in the Great Fire of London in 1666. Rebuilding was not immediate, but was largely completed by 1680, finished in 1703. In 1669 a Roman tombstone, now in the Ashmolean Museum, was found. The current design is topped by a lead-covered octagonal cupola supporting a balcony and tapered spire rising to a height of . The centre of the church is in the form of a Greek cross, with four large columns. The chandelier dates from about 1777 and comes from the West Indies. As a curiosity, this is from the burial register: "“1615, February 28, St. Martin’s, Ludgate, was buried an anatomy from the College of Physicians.” (It was first noticed by Andrew Lang, in an article in "Books and Bookmen"). The Royal College of Physicians were based in Amen Corner, a few yards away from 1614 to 1666. In 1678 Robert Hooke designed a new hall in Warwick Lane, also nearby.
