After 125 years, we take a look at some of the defining moments in the history of Tower Bridge

This iconic structure has survived two world wars, berthed some of the largest ships in the world and still to this day raises its bridges an average of 800 times per year with over 40,000 people crossing it daily.

Steeped in history, Premier Inn has delved into each decade of the much-loved attraction to celebrate its big birthday, with a set of photographs that chronicle the history of this famous landmark.

Opening celebration

The opening ceremony for Tower Bridge was held in 1894, eight years after construction began. It took 432 workers to build the bridge, in excess of 70,000 tons of concrete sunk to the bed of the River Thames to support the structure and over 11,000 tons of steel provided the framework for the towers and walkways.

Contrary to popular belief, it’s not a drawbridge; Tower Bridge’s roads are too heavy for ropes or chains to pull up, so it was designed as a bascule bridge which means the roads act like two giant seesaws.

The Clean Air Act in 1956 put an end to the problem!

An intriguing sight for us now, but this Graf Zeppelin was not an unusual occurrence for Londoners on the ground in the 30s. The German-built hydrogen filled airship travelled over 1 million miles in its lifespan, and was deployed predominantly for reconnaissance missions.

It was in 1978 that the idea for the first London Marathon was dreamed up. Chris Brasher and John Disley were in The Dysart Arms pub near Richmond Park when they were discussing the success of the New York City Marathon. After checking it out for themselves in 1979, they then launched the first London Marathon on 29 March, 1981.
