Geocache Description:


The Coffin of the Effra

In autumn 1852, fishermen near Vauxhall Bridge pulled a waterlogged oak coffin from the Thames.

London was reshaping itself: the River Effra, once winding through south London, had been mostly culverted into sewers since the 1830s as the city grappled with sanitation ahead of the Great Stink of 1858. West Norwood Cemetery – one of London’s "magnificent seven" garden cemeteries, opened in 1837 – had been built close to the river’s old course.

Tracing the coffin’s brass plate led to an undisturbed grave there. Digging revealed heavy rains had swollen the hidden Effra, eroding the soil beneath until the casket broke free. It traveled through miles of underground tunnels before emerging into the Thames.

The story spread quickly – some called it a warning about building on sacred ground, while engineers used it to highlight the challenges of managing London’s lost waterways. The grave was moved to higher ground, and the Effra’s tunnels reinforced.

Today, the river flows unseen beneath the city, and the tale of the wandering coffin still lingers in local lore.
