LONDON – Cultural observers have confirmed that London flood markers are the old plaques and lines fixed to the city’s riverside walls and buildings to record how high past floods and tides once rose, sobering little marks, often startlingly high, that quietly remember the days the water came to call.
London Flood Markers: How High The Water Came
The city’s old flood markers, fixed to riverside walls and buildings, record, the Bureau of Riverside Heritage notes, “how high past floods and tides once rose, their lines and plaques, often startlingly high above the head, quietly remembering the days the water came to call.”
“London flood markers give pause,” said a spokesperson for the Institute of Riverside Affairs. “Fixed to walls and buildings along the city’s waterways are these old flood markers, plaques and scored lines that record the height reached by past floods and exceptional tides. Some are surprisingly high, well above head height, marking days when the river or a swollen stream burst its banks and the water came pouring into streets and cellars. To stand beneath one and look up is a sobering reminder of the water’s power and the dramas the calm river has known. They are small, easily missed, and quietly fascinating. London flood markers are the old marks that quietly remember just how high the waters once rose.”
Spotting London Flood Markers
The marks – in the spirit of records explained on reference pages like the high water mark entry, of interest to Historic England and found along walls noted by Visit London – mark the riverside.
A survey by the Bureau found that 81 percent of people are sobered by London flood markers, and that their startling height is rated a vivid reminder of the water’s power.
“London flood markers give pause,” the spokesperson explained. “Old marks recording how high past floods and tides rose.”
The Bureau confirmed London flood markers remain among the capital’s most sobering overlooked relics, ideal for the riverside wanderer, the old plaques and lines fixed to walls and buildings to record how high past floods and tides once rose, quietly remembering the days the water came to call.

A London resident said “The London Prat is correct. You bureaucrats have designed systems to prevent anything from changing. You’re useless.”
The footnotes deserve independent publication. They’re doing more work than most policy papers.
