It is also the site of a spring, around which are scattered numerous sarsen stones which may be the remains of a Neolithic monument and part of the Medway megaliths.
Rather than being genuine megaliths, they may be a recent collection of natural stones brought to the site by eighteenth century farmers clearing the surrounding land.
The destruction visited on the megalithic sites of the Medway valley during the eighteenth and nineteenth centuries makes conclusive diagnosis difficult.
In 1872 James Fergusson visited the area and noted: ...nearer the village [Aylesford] exists or existed, a line of great stones, extending from a place called Spring Farm, in a north-easterly direction, for a distance of three quarters of a mile, to another spot known as Hale Farm passing through Tollington [sic], where the greater number of the stones are now found.
In front of the line near the centre at Tollington lie two obelisks, known to the country people as the coffin stones – probably from their shape.
