This is my first sketch at The Charterhouse, as a guest of the Preacher, Reverend Robin Isherwood.
The building on the right is the Great Hall, Tudor, around 1600. Beyond it is a Barbican tower, 1970s.
The small dome is the roof of the Chapel of The Charterhouse, 17th Century, by Francis Carter. According to Pevsner*, Francis Carter had “previously worked at Trinity College Cambridge, and from 1614 was chief clerk of the King’s Works under Inigo Jones.”
