C11 font at nave crossing probably from earlier church now within ramparts of the castle (q.v. 6/1), square with plait rim and figure heads at angles, west and south face decorated, that to south with 3 cats. (St. Felix, died 648, by one tradition is said to have started his mission to East Anglia c630 at Babingley 1.5km to north).
The font is situated in a prominent position within St Lawrence's Church, Castle Rising. This church is in essence Norman. However, it is generally believed that the font was originally located in a much earlier village church that was lost during the building of the earthworks of the nearby medieval castle. That older church was dedicated to St Felix - hence the feline imagery. The font may well be 1300 years old, dating back to Saxon times.
