Castle Hedingham was the scene of an immense battle on Sunday as six teams took on the Clash of Knights Triathlon.
The teams, dressed in full medieval battle gear, took part in three warrior-worthy contests, the day held in aid of national charity Samaritans.
Historia Normannis, a 12th century re-enactment society, organised the day, and have already raised £400 for the charity from the event with more likely to follow.
A percentage of the ticket sales from the day is to be donated by the castle to local charity East Anglia’s Children’s Hospices, with both charities also collecting on the day.
The main event was a gruelling 5km race, which involved a biathlon style archery contest in the middle.
The race, undertaken in full chain mail, was sandwiched in between outbreaks of fighting from the competitive knights.
Simon Orr, general manager of the castle, was very pleased with the day.
“I didn’t know what to expect but it was really good fun.
“Six hundred people turned up and everybody seemed to enjoy it.
“It was spectacular and to me looked absolutely exhausting.”
As well as the triathlon, visitors enjoyed guided tours of the castle, falconry displays and chances to have a go at medieval archery.
