Blackwell Point has been described as a probable Artillery Fort, and also as a probable Chain Tower.

There are no visible remains.

Description

A boom was put across the Thames at Blackwall with fortlets on both banks as part of London's defences against the Spanish armada. Known from a 16th century map by Adams although not reported in official records of the defences of the Thames. There were also gun emplacements at Woolwich and Erith and the fort at Tilbury. (Greater London HER)
Comments

Appears to be portrayed as a star shaped work, presumably earthwork, with a boom or pier into the Thames with possibly 2 artillery pieces on the end of the pier. As with some of the maps associated with Henry VIII coastal fortifications it may be these were proposed rather than actual defenses although London would have had the resources to build, arm and man such defences.

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.
