Fan favourite Stradivarius, the winner of more than £3.4 million in prize money, has been retired.
For years the chestnut starred on the track with jockey Frankie Dettori, taking three Ascot Gold Cups which topped their list of achievements.
Stradivarius, who landed the summer feature by ten lengths two years ago, won 20 races from 35 appearances on the track. Among the haul was four Goodwood Cups, three Lonsdale Stakes and two Doncaster Cups.
