FOUR and a half centuries to the day, the Viscount and Viscountess De L'Isle yesterday celebrated the anniversary of Penshurst Place, near Tonbridge, being gifted to their family, the Sidneys.

They were joined for the occasion by actor and historian Robert Hardy, who opened a new exhibition to mark the milestone in the stately home's long and impressive pedigree.

It was on April 25, 1552, that Sir William Sidney became owner of Penshurst Place when it was given to him by Edward VI. Many turbulent times were to follow, such as the attempted invasion by the Spanish Armada, the English Civil War and the plague, but throughout it all the Sidneys kept their hold on Penshurst.

Mr Hardy, who had taken time out from filming for the next Harry Potter movie and who has acted in several historic dramas filmed at Penshurst Place, said it was "an extraordinary achievement". He praised the family's tenacity and particularly the efforts of the present Viscount and his late father to restore and preserve the medieval manor.

The new exhibitionreflects something of the Sidneys' royal associations and the 17 generations who have lived at Penshurst Place.

To further commemorate the occasion, Mr Hardy planted a mulberry tree in the gardens, assisted by the head gardener Anthony O'Grady. The house, gardens and exhibition - Penshurst Place: a family home for 450 years - are open to the public daily until November. Further information is available by calling 01892 870307.
