How long is River Thames?

The ancient name of the River Thames was Tamesis. Tamesis is a Latin word derived from the old Celtic word, 'Tamesas' meaning dark. It is perhaps that the water of the River Thames appeared dark and cloudy.

According to scientists, the River Thames is considered to be as old as 58 million years. One of the earliest people to write about the Thames was Julius Caesar, the Roman emperor, after his journey to Britain in 54 BC. He described the river as challenging to cross.

Interestingly in the past, the River Thames used to freeze regularly during winters. This led to the initiation of ‘Frost fairs’ where various shops and activities were performed. Skating was one of the favorite pastimes for Londoners back in the winters between 1550 and 1750.

The course of the river as we know it today was acquired only 10,000 years ago. Before this, the River Thames has changed its system multiple times over a million years. This change in the river’s course is due to various reasons, the prominent reason being the rise in sea level.

The length of the River Thames is 215 mi (346 km)! Yes, you heard that right and if you cannot decipher the distance, let us help you do the mathematics. Two hundred and fifteen miles of rivers would roughly be the distance between London and Middlesbrough.

Yes, it's that long. London is not the only city that the River Thames travels through. It is the second-longest river in the UK after the River Severn, the longest river which is 220 mi (354 km).

The mighty Thames begins in Gloucestershire at Trewsbury Mead (near Cheltenham) and ends in Essex between Whitstable and Foulness Point. The river also flows through seven counties: Wiltshire, Oxfordshire, Gloucestershire, Berkshire, Surrey, Buckinghamshire, and Greater London.

Besides this, another interesting fact about the Thames is that it can be divided into two parts- Tidal and Non-tidal. The tidal Thames spans 68 mi (109.4 ) from the river’s mouth to Teddington Lock.

At the same time, the non-tidal stretch of the river begins from Teddington Lock up to Thames Head in Gloucestershire. This phenomenon is also called high spring tides.

The Environment Agency usually advises not to swim in the tidal section of the Thames. The river gets cleaner towards the west, and places like Hurley lock, Medmenham, Shiplake are the best places to swim. About 200 bridges cross the River Thames in various locations. Tower Bridge, London Bridge, and Westminster Bridge are among the most well-known bridges.

Henley Bridge, built-in 1768  between Oxfordshire and Berkshire, is known for its five elliptical stone arches. The Royal Regatta takes place around this bridge.

The catchment area of the River Thames is 4,995 sq mi (12,936.9 sq km) in total, and if the River Medway is included as a tributary, the entire catchment area increases up to 5,924 sq mi (15,343 sq km).

The width of the Thames varies from place to place. As the river goes further downstream, the width increases. The River Thames is the widest and broadest strictly at the river's mouth which measures up to 18 mi (28.9 km). It is the narrowest in Lechlade, where the Thames river counts only to 59 ft (18 m).

From which country does River Thames originate?

The source of the Thames river is generally said to be at Thames’s Head. Thames Head is a group of seasonal springs. Spring is a place on the Earth’s surface where water flows from an aquifer. Springs are an essential source of water for humans.

Thames’s head grows at Coates, Gloucestershire, England, around three miles southwest of Cirencester in the Cotswolds. Yet another highly quoted source of the River Thames is Seven Springs near Cheltenham.

This is the place where the River Churn rises. The springs at Seven Springs flow throughout the year and have been said to be one of the places from which the River Thames originates.

Thus, the River Thames originates in Gloucestershire, England, and then it flows into the North Sea where the River Thames ends via Thames Estuary.

Why is it called the royal river?
