One of the features of the Sussex sporting calendar is celebrating its 100th birthday.
The Royal International Horse Show was first held at held at Olympia
The Royal International Horse Show, which opens at Hickstead on Wednesday, is marking its centenary year.
The six-day event, first held at London Olympia in 1907, has also been staged at Wembley Stadium and the National Exhibition Centre (NEC) in Birmingham.
It moved to the All England Jumping Course in Hickstead in 1992 because of raising costs.
It was a popular part of the "society season" when it was started in 1907 by the Institute of the Horse and Pony Club, the forerunner to the British Horse Society.
Only the two world wars have interrupted the show since then.
The Princess Royal is expected to visit this year's event which runs from 25 to 29 July.
Hickstead owner Douglas Bunn said: "Fifteen years ago I offered to re-home the Royal International at Hickstead, and I am delighted I did.
"The show's history, and the scope of its programme, is ideally suited to Hickstead.
"We have worked hard to maintain and improve its image as a traditional horse show and it is wonderful to be able to celebrate its centenary."
