English: Carving, and interior of Chapel of the London Charterhouse. Pen and ink drawing by Charles Raymond Booth Barrett.

"Preserved in the Chapel is a most interesting fragment of the tomb of the founder or co founder of the Carthusian Monastery: Sir Walter de Manny or Mauny. Manny was knighted in 1331, and summoned to Parliament as a Baron in 1345 — his title being Lord de Manny. He died on 15th January, 1372, and was buried in Charterhouse.

His arms, as shewn on the carvings, were: Or, three chevronels sable. A bull of Pope Urban VI., dated 1378, mentions Northburgh (Bishop of London) and Manny as co-founders of Charterhouse.

The interior of the Chapel is, however , as full of interest as its exterior is devoid of architectural beauty. The carved oak stall-heads, the organ case, the screens, and the various monuments are worthy of close study. But the chief point is the Monument of the founder, Thomas Sutton, in the north-east corner of the north aisle. The curious alms-box in the upper part of the altar rails is of most uncommon type. A ruined aumbrey, behind the panelling on the south side of the altar in the east wall, proves this wall to be of pre-Reformation date."
