The Rolex Series continues in Italy from May 27–31 with one of the most iconic and historic events in international show jumping: the CSIO Roma Piazza di Siena. Held in the spectacular setting of Rome’s Villa Borghese, the event celebrates a remarkable milestone in 2026, its 100th edition.

First staged in 1926, the Official International Horse Show of Rome has become one of the sport’s most prestigious and traditional competitions, welcoming generations of the world’s greatest riders to compete in one of the most beautiful arenas in show jumping.

This year, seventy-six riders and 190 horses representing twenty nations will take centre stage in Rome’s most famous arena from Wednesday 27 May until Sunday 31 May, confirming the CSIO Roma Piazza di Siena as one of the highlights of The Rolex Series calendar.

Blending world-class sport, history, elegance and Italian heritage, the CSIO Roma Piazza di Siena offers a unique atmosphere unlike any other event in the sport. The highlight of the week will once again be the Rolex Grand Prix on Sunday at 12:30 PM, where many of the world’s leading riders will compete in the heart of the Italian capital.
