The Knights of Middle England are performing at Hedingham Castle for the first time.
Wearing bold and bright costumes, they will thrill the crowds with their stunts such as saddle falls, drags and rearing horses.
There will also be archery and birds of prey demonstrations, craft stalls, musicians, donkey rides and food and drink.
No dogs are allowed at this event because the birds of prey may attack them.
The event, from 10am until 5pm, will take place on Sunday and Monday and tickets cost £12.50 for adults, £9 for children and a family ticket is £37.
