St. Ninian's is a church in the Redwall series by Brian Jacques near Redwall Abbey. In the book Redwall it is inhabited by the hordes of Cluny the Scourge and is later destroyed in the book The Pearls of Lutra.
StNinian is often referred to as the apostle of the northern Britons and Picts.
StNinian stayed at the abbey for some time and was encouraged and helped in his work by St Martin who became his friend and left a lasting impression on him.
StNinian used this church for his base and from it he and his monks evangelized the neighbouring Britons and the Picts.
