It was 90 years ago this month – 6th and 7th January, 1928 – that the River Thames flooded disastrously in what was the last major flood in central London.

Fourteen people are reported to have died and some 4,000 made homeless when the river burst its banks and spilled over the top of the Thames Embankment. Part of the Chelsea Embankment collapsed.

The flood – which was blamed on a range of factors including a sudden thaw upstream, heavy rain, a tidal surge and the impact of dredging – peaked at about 1.30am on 7th January at a height of 18 foot, three inches (5.56 metres) above ordnance datum.

The city saw extensive flooding on the City of London itself as well as in Southwark and as far upriver as Putney and Hammersmith and downriver in Greenwich and Woolwich as well as beyond.

Most of the deaths occurred when the embankment gave way near Lambeth Bridge and a wall of water swept through the slums on the Westminster side of the bridge with 10 people losing their lives.

Among the buildings flooded were the Tate Gallery at Millbank – where many works including some by JMW Turner were damaged, parts of the Houses of Parliament including Westminster Hall and the House of Commons, numerous Underground stations and Blackwall and Rotherhithe tunnels. The moat of the Tower of London, dry for 80 years, was filled.

While the flood waters receded by the end of the day, the damage took years to repair with many buildings in Millbank, the worst affected area, demolished. Embankments were raised in the wake of the flooding but it wasn’t until after the North Sea flood of 1953 that authorities took action to build the Thames Barrier (it was eventually completed in 1982).
