what happened to old london bridge

February 23, 2026

Old London Bridge hasn’t vanished—it was demolished in the 1800s, its direct successor was later sold and moved to Arizona, and scattered pieces of even older bridges still survive in and around London today.

What “old London Bridge” actually was

When people ask “what happened to old London Bridge” , they usually mean the famous medieval stone bridge crammed with houses and shops that stood for about 600 years.

This medieval bridge was completed in the early 13th century and became a bustling mini-town, with homes, shops, a chapel and even a small palace built on top of it.

It survived fires, storms, ice on the Thames and political turmoil, but over time became dangerously overcrowded and structurally fragile.

By the 1700s, it was outdated and a serious bottleneck for London traffic, both on the road and on the river.

Demolition of the medieval bridge

The medieval “Old London Bridge” was gradually stripped and then demolished in the late 1700s and early 1800s.

In the 1760s, the houses and shops were removed to widen the roadway and reduce the fire risk, destroying the classic “crowded bridge” look seen in old illustrations.

Even without the buildings, the 600‑year‑old structure was expensive to maintain and its narrow arches obstructed river traffic, so it was fully replaced by a new bridge designed by engineer John Rennie.

A design competition was held in 1799, Rennie’s design won, and the medieval bridge was finally taken down when the new bridge opened in 1831.

The “new” 19th‑century London Bridge and Arizona

The Rennie bridge , opened in 1831, is also sometimes called “old London Bridge” today, because it too no longer stands in its original place.

By the mid‑20th century, this 19th‑century bridge was no longer adequate for modern traffic and was sinking slowly into the Thames.

In the late 1960s it was famously sold to American businessman Robert P. McCulloch, dismantled stone by stone, shipped to the USA, and rebuilt in Lake Havasu City, Arizona, where it still stands as a tourist attraction.

The bridge in central London today is a more functional concrete structure from the 1970s, not the one in the nursery rhyme or the one in Arizona.

Where bits of old London Bridge are now

Although the medieval bridge was demolished, its stones were reused or dumped rather than neatly preserved.

A lot of masonry was tipped into the Thames as rubble, and for years there were reports of ships hitting submerged remains.

Other pieces were recycled into buildings and structures around southern England; examples include:
- Ingress Abbey in Greenhithe, Kent, which prominently uses stone from the old bridge in its construction.

* Balustrades and stones reused in places like Herne Bay in Kent (since removed), and in properties in areas such as Wandsworth and possibly near Stoke Newington.

Modern historians and London enthusiasts have tracked down scattered fragments, so in a sense the medieval bridge is “everywhere and nowhere” at once.

Forum & “trending topic” angle

The question “what happened to old London Bridge” has had a bit of a pop‑culture revival online because of explainer videos and discussion threads.

A popular YouTube episode by the “Map Men” duo breaks down the history and quirks of Old London Bridge, sparking comment threads about the bridge, British TV nostalgia, and even editing jokes.

Reddit discussions often mix genuine curiosity about the bridge’s fate with chat about the videos’ humor, ad cues, and references to the “London Bridge is falling down” nursery rhyme.

So when people search “what happened to old London Bridge” today, they’re landing on a mix of serious historical explainers, tourism pieces, and lively forum conversations linking the history to modern media.

In short:

The medieval Old London Bridge was stripped of its buildings in the 1760s and demolished when a new bridge opened in 1831.

The 19th‑century London Bridge that replaced it was later sold, moved, and rebuilt in Lake Havasu City, Arizona.

Fragments of the medieval bridge live on in the Thames and in scattered buildings across London and the southeast of England.
