On the north side of Green Court, set back from the main property line, stands 25 The Precincts (Image 1). It is located on the site of part of the former brewhouse, and was built in 1635 of chequered flint and Caen stone blocks. It has become known as the Cromwellian House.
The date is rendered in red brick set in the flint and Caen stone surround - it is very easy to miss it (Image 2). Each year new boys to King's school, when given a tour of the buildings, are invited to find the date - it helps if you've had an older brother or sister at King's!
