In its thousand-year history Leicester Cathedral has been home to many secrets. Now eagle-eyed visitors can spot a new one in the Cathedral's colourful windows.
Celebrated stained-glass artist Tom Denny was commissioned to create two windows for St Katharine's Chapel in the Cathedral to commemorate King Richard III.
The monarch, who is one of England's most famous and controversial kings, was laid to rest in the cathedral two years ago after being unearthed underneath a car park in the city.
But unknown to Cathedral staff, Mr Denny had added a reference to a rather more recent piece of Leicester history.
Shortly before the windows were installed last year the artist decided to add in a tiny picture of a football in a nod to Leicester City's unexpected triumph in the Premier League - even though the team had not yet won.
Mr Denny said: "At this point they still had three or four matches to go until the end of the season.
"There was an almost instant upsurge in the fortunes of the club as soon as he was buried there.
"It was rather like the middle ages, when people venerated the bones of a saint."
It was actually Mr Denny's wife, Benita, who was behind the decision. "She came into the room and said 'you still haven't put in a reference to the football'" he said.
"I was chancing it, because they might not have won."
Cathedral staff only discovered the football after the windows were in place, but luckily for Mr Denny they were delighted.
The thumbnail-sized image is in the far right-hand corner of the window, and is only visible from one place in the Cathedral - the steps leading up to the altar.
It shows the football in the grounds of Kirby Muxloe Castle, which was owned by Lord Hastings, who was executed after being accused of treason by the king in 1483.
This week Leicester manager Claudio Ranieri visited the cathedral and was shown how to spot the football.
Mr Denny's inspiration for the window was imagining hot-tempered Leicester City striker Jamie Vardy kicking the ball so hard it flew out of the stadium and landed in the grounds of the castle.
Though he is based in Dorset, Mr Denny became a Leicester City supporter after he was commissioned to do the window - though before, he says, the team's astonishing season of wins.
But, he says, this is not the first time his windows have brought luck to a struggling football team. In 2005 he was commissioned to design three windows for Sunderland Minster.
The team had recently been relegated from the Premier League and their 2006-2007 season in the Football League started badly, with four consecutive defeats in August.
But after Mr Denny's windows were installed the team turned the season around and escaped further relegation.
Pete Hobson, director of the cathedral's regeneration project, hinted that Leicester may have had an even greater power than the dead king on their side.
"We were in search of donors to support the project and we'd been in conversation with the owners of Leicester City. Fairly late on the owner Vichai Srivaddhanaprabha made an extremely generous personal donation - and that was also around the time their season began to pick up," he said.
However, he was a little more sceptical about any direct link. He said: "My theology does not make me think that either God or Richard made Leicester City win.
"Nobody can quite explain why they started winning just as Richard was reinterred."
The medieval king, who died fighting Henry Tudor at the Battle of Bosworth in 1485, was found under a city council car park in Leicester in 2012 after a project to recover his remains.
After a battle with a group who said they were Richard's descendants and wanted him to be buried in York Minster, Leicester Cathedral was announced as his final resting place in 2014. ENDS
