However, within a decade Henry's engagement in the Wars of the Roses meant that funds began to dry up. By the time of Henry's deposition in 1461, the chapel walls had been raised 60 ft high at the east end but only 8 ft at the west; a building line which can still be seen today as the boundary between the lighter stone below and the darker above. Work proceeded sporadically until a generation later in 1508 when the Founder's nephew Henry VII was prevailed upon to finish the shell of the building. The interior had to wait a further generation until completion by 1544 with the aid of Henry VIII. The chapel would be the only part of Henry VI's "Founder's Will" to be realised.
