Mersea Stone, East Mersea has been described as a certain Artillery Fort.

There are earthwork remains.

This site is a scheduled monument protected by law.


Tudor blockhouse surviving as a faint earthwork. The site was recognised from the air and subsequently surveyed. It has been partially destroyed by construction of the sea wall. The fort was built in 1547 and appears to have been an earthen structure - there is no evidence for brick or stonework. It was abandoned in 1552, refortified in the 1580's and still in use in 1631. It appears on a map dated to 1656, around the time it finally fell into disuse. The remainning earthwork survived to be recorded by the OS in 1897. (PastScape – ref. Eddy, Milton and Priddy, 1983)

Fort with 4-6 guns, ditch and drawbridge built in 1547. It was allowed to fall into decay but repaired in 1587 and was still considered effective in 1631. By 1656 it was in use as a house, and so was not demolished the previous year (Sier) It is shown on a map of 1656. Holman describes it as decayed in 1710. Morant says it was ruinous in 1768. A single turret is visible from the air in the saltmarsh beyond the sea wall. Archaeological Survey of Cudmore Grove Country Park in 2002-3 looked at some timbers near the blockhouse. (Heppell, 2002) According to Kent a battery was built c.1796 into the seaward face of the old fort at East Mersea. This battery had 6 24 pounder guns. Management recommendations in 2005 recognised that the main risks to the site were sea wall construction and erosion either by nature or by increased visitors. The site needs to be monitored regularly for erosion and any archaeological strata revealed by erosion needs to be investigated (Heppell, 2005). (Unlocking Essex's Past)

Minor archaeological investigations, such as watching brief reports, and some other 'grey' literature is most likely to be held by H.E.R.s but is often poorly referenced and is unlikely to be recorded here, or elsewhere, but some suggestions can be found here.
The possible site or monument is represented on maps as a point location. This is a guide only. It should be noted that OS grid references defines an area, not a point location. In practice this means the actual center of the site or monument may often, but not always, be to the North East of the point shown. Locations derived from OS grid references and from latitude longitiude may differ by a small distance.
