Pre 9 May 2022. Off-shore Dredging.
Found at Greenhithe Wharf amongst material from this area and Licence Area 461 (East English Channel Region):
1 post-medieval iron 3-pounder cannonball. A large flat area from when it was cast suggests it probably dates to the second half of the 17th century.
2 World War One to World War Two navel shells. Both appear to have been fired but are not closely identifiable (their c.80mm diameter equating to 3", which was a common calibre/mounting on British warships).
See Discovery Reports (S9) and (S10) and reporting protocol annual report (S11) for further details.

Found at Frindsbury Wharf, amongst material from this area and Licence Area 461 (East English Channel Region):
