NHER 45365 (Monument record) - Glacial erratic boulder

Glacial erratic boulder on grass triangle outside watermill.
Local folklore states that this stone marks the centre of Norfolk but this belief has not been traced before the 20th century.
A local antiquarian, Dr. Puddy recorded that the triangle of land that contains the stone was formed around the time of the Inclosure Act in 1815 but does not mention the stone (S1).
A search of historic maps indicates that the stone does not appear on the Hoe Tithe Map (S2) or the First Edition Ordnance Survey Map (S3), but the word "stone" does appear on an unsourced map accessed via www.oldmaps.co.uk and stated to date to 1891.
A letter written to the Eastern Daily Press newspaper in 2002 (S4) states that the stone was in this location in the late 1920's. However, it does not appear on the 1928 Ordnance Survey map. The Ordnance Survey did usually mark large stones at that time, but it's possible that this one may have been overlooked.
Dr. Puddy lived at the Mill House around the 1890's and many stone objects from his antiquarian collection remain at the mill. It's possible that he may have aquired the boulder and placed it in its present location but there is no known documentation to support this.
Information from correspondence (S5).
