St. Andrew Undershaft
Constructed in 1532, St Andrew Undershaft is a rare example of a City church that survived both the Great Fire of London and the Blitz. The unusual name of the church comes from the fact that a maypole once stood nearby, so the church stood literally 'under the shaft' of the maypole. Unfortunately, the church is normally closed to the public, but you can make arrangements for access with St Helen's Bishopgate, who now run the church.
