The Viharamahadevi Park (formerly Victoria Park) is a public park located in Colombo, next to the National Museum in Sri Lanka. It is the oldest and largest park of the Port of Colombo. Situated in front of the colonial-era Town Hall building, the park is named after Queen Viharamahadevi, the mother of King Dutugamunu. The park was built on land donated to the Colombo city by Charles Henry de Soysa during the British rule of Sri Lanka, and used to be named "Victoria Park" after Queen Victoria. During World War II it was occupied by the British Army with Australian 17th Brigade based at Victoria Park. After the war the park was restored and open to the public in 1951.
