The Tower of London is set to restore water to its moat for the first time in nearly two centuries, in a major redesign that blends heritage, ecology and public access. Plans approved by Tower Hamlets Council will transform the dry moat into a landscape of ponds, wetlands, meadows and rain gardens.
A moat with a murky past
The Tower’s moat has been dry since the 1840s, when it was drained after becoming notoriously foul-smelling. Before that, the ditch had long served a defensive and practical purpose, but centuries of silt, waste and poor drainage left it unusable as a water feature.
What the new plan includes
Historic Royal Palaces says the project will create an “ecologically rich moat landscape” that responds to biodiversity loss and water scarcity. The redesign includes wetlands, grassland areas, rain gardens on the west side, and a nature learning pond for school visits in the east moat.
The plans also include memorial installations linked to the First and Second World Wars, plus a gathering area and open meadow near the entrance to improve the visitor experience.
Part of a wider revamp of the Tower of London
The moat restoration is part of a broader £70 million redevelopment of the Tower of London. That wider programme will add new community spaces, learning centres and public access to the site’s architectural archive, alongside improvements aimed at education, sustainability and conservation.
By turning the moat into a living ecological space, the Tower is reworking one of London’s most famous historic features into something that serves both the site’s past and its future.
