About the The Crypt Museum
A museum is the crypt underneath the City of London's oldest church.It shows off the history of the church itself, but also has a number of Roman artifacts, including a mosaic floor.
It's surprisingly large, and delightedly dimly lit for a very atmospheric appearance.
Note that the museum is closed during church services.
