This incredible silver-gilt model of a tower is actually a salt cellar. The body of the tower is fitted with small drawers which would have been used to hold salt and spices. It was presented to Charles II for his coronation by the Parliamentarian stronghold of Exeter, possibly as a conciliatory gift.
From 8 December 2017 to 13 May 2018 the Salt is on display in The Queen's Gallery, Buckingham Palace.
