The river Thames ​ — affectionately known as Old Father Thames — ​ rises from four headstreams in the picturesque Cotswold Hills of south - central England.
Thamesi jõgi, mida hellitlevalt Vanake Thamesiks kutsutakse, saab alguse neljast allikast Cotswold Hillsis Lõuna - Inglismaa maalilises keskosas.
