More than 300 rarely-seen objects spanning two millennia will be revealed in new, permanent gallery at Waddesdon Manor.

From a 1st-century cameo of Augustus Caesar’s grandson, to a microscope used by entomologist and flea expert Charles Rothschild, via jewellery given as presents from Queen Victoria, to objects bearing Nazi inventory numbers, gold boxes, silver and jewellery – a new gallery with a permanent display of items that celebrates the Rothschild family as collectors of extraordinary objects will open at Waddesdon Manor on September 7.

Baron Ferdinand de Rothschild built Waddesdon at the end of the 19th century in the style of a French Renaissance château, suggesting that he had a keen eye on the past.

He was part of a long line of remarkable Rothschild collectors, a dynasty which continues to collect to this day.

The collections range from paintings and decorative arts to textiles, books and manuscripts - but this new, purpose-built gallery in Ferdinand’s magnificent house in rural Buckinghamshire celebrates a different passion.

It showcases over 300 precious objects dating from 100AD to the 20th century, all of which have personal connections to family members past and present.

More than three-quarters of them are on loan from the private collection and will be on public display for the very first time.

All the objects have been cleaned and, in some cases, conserved as part of the gallery project, leading to a wealth of new knowledge and discoveries.

All the objects have an intimate connection to the Rothschild family, from Baron Ferdinand’s watch chain and Miss Alice’s seal, to classical coins collected by James de Rothschild and the microscope used by Lord Rothschild’s grandfather, the naturalist Charles.

Particular highlights include an amber casket made in the 17th-century in the Baltic, a mounted nautilus shell that belonged to the renowned collector William Beckford, an 18th-century Mughal jade vase encrusted with precious stones and the Nelme Cup, a unique gold standing cup made in England in 1727.

Lord Rothschild says: “I am truly delighted that the Treasury, the culmination of a long-held family ambition to extend the displays at the Manor, is opening this autumn.

“Many objects from my family’s collections, all with significant and personal connections, are being put on show for the first time.

“The display is a homage to the Rothschilds who created and have cared for Waddesdon, and an expression of the ties which bind earlier generations to the present.

“I also hope that this new room, with its extraordinary and varied contents, will surprise, delight and intrigue our visitors as they explore.

“Even for those who think that they know Waddesdon and its collections well, there is much to discover.”

Pippa Shirley, head of collections at Waddesdon Manor, said: “The Rothschilds were collectors extraordinaire, and this small, intense room is a microcosm of an aspect of their taste, curiosity and discernment.

“But behind the beauty of the objects themselves is something more.

“This is nowhere more true than in A Rothschild Treasury, where every object tells a story – of its making, of its passage through time and of the family thanks to whom we can now enjoy it.”
