River Thames has been a major landmark in London for centuries. It is England’s longest river and the second longest in the United Kingdom. Here are 10 interesting facts about a River that is famous all over the world. The famed River is non-tidal in certain areas and tidal in some, that is, its tides can be compared to that of the ocean.

It becomes tidal from Teddington until it runs into the Thames Estuary (part of the North Sea). Click the next ARROW to see the next photo!
