In 1862 a small stone sundial was discovered on the site of the church of St. Martin-Le-Grand on the west side of Market Square when several adjoining houses were pulled down and some remains of the ancient fabric of the historic church were revealed. The sundial is formed of a cube of fine grained oolite, measuring about 12cm in each direction. The date of this sundial is unknown but it may be Roman or Early Medieval.
