Wellington Arch stands as a striking example of neoclassical architecture in London. Originally designed by Decimus Burton, the arch was completed in 1826 to serve as an impressive gateway to Buckingham Palace. Its rich history includes a variety of transformations and fascinating uses over the years.
In 1846, the arch was topped with a massive equestrian statue of the Duke of Wellington. However, this statue was eventually considered too large for the structure. In 1882, a major road widening of Piccadilly provided the perfect opportunity to move the oversized statue to Aldershot. In its place, a new sculpture, "Peace Descending on the Quadriga of War," was installed in 1912. This magnificent statue remains the largest bronze sculpture in the United Kingdom and is beautifully illuminated at night.
During the 1950s, Wellington Arch took on an unusual role as the smallest police station in the city. It housed ten constables, two sergeants, and even a cat, providing a unique glimpse into the adaptability of this historic structure.
In 2001, after an extensive £1.5 million restoration by English Heritage, the arch was opened to the public for the first time. Now, visitors can explore its storied past and enjoy breathtaking views from the spacious balconies, offering dramatic vistas down Constitution Hill and across central London.
