Nestled in the heart of Southeast London, One Tree Hill Nature Reserve offers a serene escape from the hustle and bustle of city life. Situated in Honor Oak and accessible by Overground train, this charming 7-acre reserve boasts an interesting history, diverse wildlife, and stunning panoramic views of the city. From the summit, visitors can enjoy a sweeping vista that includes landmarks such as The Shard, St. Paul’s Cathedral, and Canary Wharf.

One Tree Hill holds a significant place in London’s history. The hill is believed to be the site where Queen Elizabeth I once rested under an oak tree on Mayday in 1602. The hill’s name originates from a lone oak tree that once stood there. Though it has been replaced over the centuries. The current oak tree was planted by the Camberwell Borough Council to commemorate the opening of the park to the public in 1905.

During the English Civil War One Tree Hill served as a strategic viewpoint and later became part of the Great North Wood, an ancient woodland that once stretched across South London.

You will find an octagonal concrete structure which has the appearance of a bandstand on top of One Tree Hill, but it was not its original use, although it may have been used by brass bands in later life. It was actually built in 1916 in order to mount a Royal Naval gun to defend London against bombing raids from German Zeppelins and Gotha bi-planes.

Bolts of the mounting ring which supported the gun can still be seen, together with a groove in the radiating line of bricks where a lightning conductor was installed.

In 1916 the Royal Naval Air Force and the Royal Flying Corps shared anti-aircraft duties, and two watches of 10 men from Naval crews were stationed here to man this gun. From the two known eye-witness accounts, the gunners may have not been successful in shooting down a Zeppelin but might have instead caused damage to tramlines near Peckham Rye Common from a missed shot!

Despite its small size, it is a haven for biodiversity, and for those interested, it is also a popular spot for birdwatchers. During our recent visit, we spotted an abundance of blackberries that are due to ripen in the next couple of weeks, making it an excellent spot for berry picking.

One Tree Hill Nature Reserve is a testament to the rich history and natural beauty that can be found in London’s lesser-known green spaces. Whether you’re a history buff, a nature lover, or simply looking for a peaceful spot to enjoy a walk, One Tree Hill provides a perfect escape within the city. A hidden gem well worth exploring.
