Monument record FRS 025 - 2 Possible landing stage/pier/jetty

Two possible piers or landing stages, of unknown date, are visible as possible timber structures extending from the shore out onto the intertidal mud southeast of Black Heath house; the longer structure extending from TM 42335775 to TM 42325766 (c.90m x c.2m) and the shorter structure extending from TM 42335775 to TM 42335772 (c.35m x c.2m), although it may extend further to TM 42335771 (totalling c.45m) where there are two posts similar to those in the main body of the structure. Although the longer structure is visible on 1943 photography (S1), it is only with the 1969 photography that the shorter structure is visible and both structures are shown in some detail (S2). The longer structure comprises a solid area where it meets the shore (possibly surviving planking or a solid 'foot' to anchor the structure to the shore) and pairs of posts, spaced at c.3m intervals, extending out into the estuary. By 1969, the southern half of these posts were being visibly eroded away. The shorter structure has no solid area (although, unlike the first structure, this one seems to disappear into the shore, suggesting that it way extend further northwards) but does also have pairs of posts, although these are spaced at c.1.2m intervals. The presence of two isolated posts and a pair similar to those in the main part of this feature, south of the main part, suggests that the structure may well have extended further southwards.
Also seen as part of field survey of coastal area - two lines of very regular parallel posts, sawn off to height of c.25cm. Runs alongside E of very recent jetty. Also a further 6 or so posts at end of existing jetty, sawn off and not of any great age but probably unconnected with the jetty. S3
Boathouse, slipway and tramway are marked on pier in 1900 (S4) and 1920 (S5)
