Taken from Wikipedia: St Maddern’s Church is the parish church of Madron, near Penzance in Cornwall and was once the mother church of Morvah and Penzance. It is a Grade I listed building. The church is a large building of the 15th century; however it retains some 14th century work in the chancel. The font bowl (disused) is said to be Norman and there are a few old bench ends.
