<P> The Exeter Salt, a 45 - centimetre (1.5 ft) tall salt cellar in the form of a castle on a rocky outcrop, was presented to Charles II after the Restoration by the city of Exeter . Each of its four main compartments, in the turrets, held about 29 g (1 oz) of salt, and smaller compartments in the walls held pepper and spices . It was made in 1630 by a German goldsmith in Hamburg and is set with 73 gems . Eleven smaller salts named after St George were originally made for a St George's Day banquet of the Knights of the Garter and Charles II in the 17th century . Another, the Queen Elizabeth Salt, was made in 1572 during the reign of Elizabeth I for a member of the aristocracy; it was acquired by Charles II . Complementing the salts are twelve salt spoons made for George IV in 1820 . </P> <P> Three silver - gilt objects which have been used at royal christenings are displayed in the Jewel House . Charles II's marriage to Catherine of Braganza produced no heir, but a font and basin made in 1661 may have been used to baptise some of his 13 illegitimate children . The font stands 95.2 centimetres (3.12 ft) tall, and the whole objects weighs 28.43 kilograms (62.7 lb). Its domed lid is surmounted by a figure of Philip the Evangelist baptising the Ethiopian eunuch . It was last used to baptise Princess Charlotte of Wales (child of the future George IV) in 1796, and the basin found a new role as an altar dish in the 19th century, while the font was used as a plinth for the Lily Font . </P> <P> A christening ewer and basin made in 1735 were used at the christening of the future George III in 1738 . His father, Frederick, Prince of Wales, had been banished from the royal court by George II and was forbidden to use the Charles II Font . An inscription at the front of the ewer records its use at the christening of George III's son, Prince Alfred, in 1780 . The handle of the ewer is topped by a figure of Hercules slaying the Hydra, symbolising the triumph of virtue over vice; it stands 45.7 centimetres (1.5 ft) tall . </P> <P> The Lily Font was made in 1840 for the christening of Victoria, Princess Royal, the first child of Queen Victoria, who declined to use the Charles II Font because of its unseemly history . The font is decorated with water lilies, symbolising purity and new life, and cherubs plucking lyres . It has been used for the christenings of all of Elizabeth II's children and grandchildren except Princess Eugenie, with holy water from the River Jordan . The font stands 43.2 centimetres (1.42 ft) tall and weighs approximately 10 kg (22 lb). </P>
