paragraph_text: Two recent discoveries indicate probable very early settlements near the Thames in the London area. In 1999, the remains of a Bronze Age bridge were found on the foreshore north of Vauxhall Bridge. This bridge either crossed the Thames, or went to a now lost island in the river. Dendrology dated the timbers to 1500 BC. In 2010 the foundations of a large timber structure, dated to 4500 BC, were found on the Thames foreshore, south of Vauxhall Bridge. The function of the mesolithic structure is not known. Both structures are on South Bank, at a natural crossing point where the River Effra flows into the River Thames.
