The Chapel, Oundle School, Northamptonshire 1954-56
John Piper (1903-92) is widely recognised as the most important post-war exponent of stained glass in Britain.
His three windows for the apse of Oundle School of 1954-56, fabricated by Patrick Reyntiens, were his first stained glass commission and remain one of his most admired.
The windows depict nine personifications of Christ and are executed in traditional mouth-blown antique glasses, their colours intensified by extensive double plating of the glass. The windows are now dulled by surface dust and grime and the plates have in numerous places been invaded by dust, moisture and insects. In 2010 the Trust compiled a full condition survey and conservation proposal.
