Yoga outside a National Trust stately home at sunset is the unusual invitation being issued to anyone who fancies joining in and helping a good cause.

Yoga teacher Veronica 'Vee' Zappia has got the Trust's permission to hold a yoga session on the lawn outside Felbrigg Hall, near Cromer, to celebrate the equinox on September 22.

Anyone who turns up is welcome to take part in the free event which will also feature a raffle, and there will be a chance to donate to the Ellen Mezzetti Memorial Fund in aid of Epilepsy Research UK.

Ten percent of whatever is collected will go to Felbrigg Hall.

Cromer student Ellen died from a seizure in her sleep, aged 16, in 2006.

Ms Zappia, 50, from Aylmerton, near Cromer, has been a yoga practitioner for more than 25 years and has taught the discipline for more than a decade.

Last year she travelled to India and taught yoga to children there.

'I always celebrate the equinoxes and the solstice and to use the lawn at Felbrigg will be magical,' she said.

'This time of year is really special to anyone who's into yoga. It goes right back into Indian tradition.'

People are invited to bring along picnics and watch, or take part. The gathering will start at 5.30pm, Ms Zappia will teach yoga from 6pm-6.45pm and the sun will set at 6.51pm.

The equinox, which happens in March and September, is the day when the hours of darkness and light are about the same.
