This commission for a new chancel at the centre of St Gallen Cathedral was won in an invited competition. St Gallen is justly famous as a long-lived monastic community with a lavish cathedral and an extraordinary library. The commission was to commemorate the 300th anniversary of the construction of the Baroque cathedral and was required to replace a temporary wooden chancel that had been there since the 1960s.
