In March 1985 a bronze brooch was found in the River Medway between the Friary and the bridge. The length of the brooch is 50mm. At the head it measures 35mm and at the foot 33mm. The hollow bow, very humped or leech shaped, is 16mm long. The head and foot each consist of a group of 3 conjoined roundels arranged in convex fashion and with scalloped edges. The underside is round but each roundel is decorated with 2 concentric circles in relief. The hinge and catch plate are set on opposite sides of the axis. They were cast with the body of the brooch. Between the 2 arms of the hinge a thin piece of wire indicates where the missing pin was attached. It appears to be an equal armed brooch of the Anglo Saxon period rather than of the Iron Age. A date of the second half of the 6th century or first part of the 7th century has been suggested by Professor Hubener. It could have been made in Kent or between the Seine and the Rhine.
