The English Stones can be seen in this picture under the far left of the bridge. Not sure why the picture is so small?
During the English Civil War, Prince Rupert was chased across the river, and the pursuing Roundheads drowned on the English Stones rocks after being assured by the ferryman of the safety of the crossing, a testament to the treachery prevailing at the time and the danger of the River Severn.
With a tidal rise and fall of around 48 feet (14.5 metres) it has the curious phenomenon associated with the lower reaches of the Severn, the tidal bore, which forms somewhat upstream of the port of Sharpness. However a tidal range greater than that of the Severn is recorded from the lesser known Ungava Bay in Canada. During the highest tides, the rising water is funnelled up the Severn estuary into a wave that travels rapidly upstream against the river current. The largest bores occur in spring, but smaller ones can be seen throughout the year. The bore is accompanied by a rapid rise in water level which continues for about one and a half hours after the bore has passed.
