Kedermister Library

The Library was founded before 1631, by Sir John Kedermister, for the benefit of “Ministers of the said town of Langley and such other of the County of Buckingham as resort thereto”. It is described in Simon Jenkins’ book, England’s Thousand Best Churches, as ‘The Jewel of Slough’.

For more information about the Library, please take the Tour of St. Mary’s.
