Many years ago i can remember taking a train to Chatham Station,walking to Rochester,over the bridge to Strood and along the road by the River.There was a steep footpath climbing up between old chalk pits.Going by O.S. maps i think this area is Frindsbury and has a church at the top of the hill.I came down again beside a creek(Whitehall?) and eventually found myself on a flat area.There was a hill(Tower Hill?)which i seem to remember being of a rock other than chalk.In this hill i seem to remember some caves which i didn't explore.Parked nearby unattended was an old green 3 axle army lorry.Any know this area and any caves that might be there and their purpose?
