The priest at Rosslyn Chapel will leave his post in July

Rosslyn Chapel in Scotland, otherwise known as St Matthew's Collegiate Church, is a functioning Episcopalian church, with a 300-strong congregation, services, baptisms, weddings, et al.

Unfortunately, since the Da Vinci Code novel was published, naming it as the hiding place of the Holy Grail, it has also become a magnet for tourists, many of whom have no concept of what a working church is about, shall we say? Or what a priest might consider improper. Or bearable.

The Rev Michael Fass, age 61, has had enough.
