The countess with the Dean of Rochester, the Very Rev Dr Mark Beach and Canon Pastor Phil Hesketh

Sophie, Countess of Wessex will do her bit to keep Rochester Cathedral standing.

The Queen’s daughter-in-law has become a patron of the Rochester Cathedral Trust after a private tour last week.

The charity was founded in 1985 and looks after the structure of the 900-year-old cathedral building, which is due its first major review in five years this summer.

She will also be involved in a campaign to raise £5 million to help music in the cathedral, which includes recruiting choristers from outside the exclusive King’s School.

Many young boys from non-fee-paying schools across Medway will be invited to join the choir for the first time as part of an outreach programme. Girls already join the choir from other schools.

The Dean of Rochester, the Very Rev Mark Beach, said: “It’s widening the net certainly.”

He added: “The Countess will be a kind of figurehead for the fundraising for the cathedral, and in particular at the moment that’s about raising money for the music endowment.

“It’s about raising the profile of the cathedral. With a royal patron you can invite people to events with the additional draw that they might meet a member of the royal family.”

The 48-year-old royal, who is married to the Queen’s youngest son Prince Edward, was brought up and educated near Tunbridge Wells.

Dr Beach said: “She was fascinated by what’s going on in the building and was particularly interested because we’re a relatively small cathedral with relatively poor resources in an economically varied area.

“She felt her contribution might be more important perhaps than working with a larger cathedral in a more affluent area.”
