Harry Potter: Secret reservoir hidden beneath exclusive London square used to film Deathly Hallows

There are many secrets hidden beneath London’s streets but some are hiding right in plain sight, like the secret reservoir that featured in the Harry Potter franchise.

The reservoir, which sits in an exclusive North London square covered by a grassy mound, is inconspicuous to passers by but just beneath the surface is a vast network of stone arches.

Claremont Square reservoir is a hidden architectural gem and a wonderful example of an 18th Century inner city reservoir.

The location also ticks a box for Harry Potter fans who are keen to visit real places where the movie was filmed, with many dotted around London.

The square is the location of Number 12 Grimmauld Place, which features in both Harry Potter and the Order of the Phoenix and Harry Potter and the Deathly Hallows.

Harry and friends emerge from behind the trees, open an iron gate and, seconds later, Number 12 Grimmauld Place appears.

It’s first seen in the magical series in Book Five, when it’s used as the HQ of the Order of the Phoenix.

It then becomes more symbolic as Harry’s first true home when his godfather Sirius leaves it to him in his will.

Claremont Square also appears again for a brief moment with children playing with the snow.

The reservoir is still intact and was emptied and covered with grass, following the construction of a larger one nearby, and houses were built around the site

The grass mound is around four metres high with steep sides and a slab-covered entrance on one side leads to two flights of stone stairs with iron handrail descending eight metres below ground level.

Potter fans who have taken in sights including the Leaky Cauldron and Diagon Alley at Leadenhall Market, Gringotts Bank at Australia House and King’s Cross Platform 9 ¾ will be keen to add this spot just around the corner from Angel Station on the map.
