The initials of Lady Anne Clifford on the east wall of St Ninian's Church ('Ninekirks') at Brougham near Penrith in Cumbria.
The original Norman church on this site was completely rebuilt in 1660 by Lady Anne Clifford, who had inherited Brougham Castle as part of her family’s estate. St Ninian's' is very similar to St Wilfred's Church at Brougham which Lady Anne had also rebuilt two years previously.
The initials AP stand for “Anne of Pembroke" because Anne was the Countess of Pembroke.
