Windleshaw Chantry in St Helens and to honour the occasion Mass was celebrated by Fr Tom Gagie, parish priest of St Thomas of Canterbury in the Lancashire town, at the ruined Chantry which falls under his supervision.
Previous Masses at the Chantry – which recent research shows was officially opened on 21 June 1415 and not in 1435 as previously thought – have been well attended. It is hoped English Heritage can be persuaded to make a grant for its partial restoration.

COUNTLESS hours of painstaking research have helped shed new light the origins of one of the town's most historic buildings.

The Windleshaw Chantry is among the oldest structures in St Helens and dates back to the 15th century.

Ted Forsyth has been working on a three-year project into its history alongside John Brereton, from Haydock and Jack Gaskenn, who passed away during the research.

Their work has involved carefully identifying the thousands of graves buried in the grounds.
