Tasked with producing a secure, yet delicate solution to house the historic ‘London Stone’, Firman Glass Projects have installed a P7B security-rated glass and masonry enclosure. 'The London Stone’ is an important landmark housed at 111 Cannon Street in the City of London. It is an irregular block of oolitic limestone, the remnant of a once much larger object that had stood for many centuries on the south side of the street. The name "London Stone" was first recorded around the year 1100, although the date and original purpose of the Stone are unknown.
