Queen’s Park in London is managed by the City of London Corporation because it is part of the Hampstead Heath estate, which the Corporation oversees under the Hampstead Heath Act of 1871. This Act gave the Corporation responsibility for maintaining and managing various open spaces to preserve them for public enjoyment and environmental conservation.

Key reasons:

1. Historical acquisition: Queen’s Park was acquired in 1886 by the Corporation of London (now the City of London Corporation) as part of its mission to preserve open spaces for the public.
2. Preservation mandate: The Corporation took over areas like Hampstead Heath and Queen’s Park to ensure they were protected from urban development and maintained as public amenities.
3. Unique jurisdiction: The City of London Corporation is distinct from local councils and has a broader remit to manage several green spaces outside the boundaries of the City of London. These include Epping Forest, West Ham Park, and Burnham Beeches, among others.
4. Public benefit: The Corporation is committed to maintaining these spaces as free, high-quality areas for recreation and leisure, and it continues to manage Queen’s Park as a charitable trust.

This arrangement reflects the Corporation’s historical role in conserving open spaces around London for the well-being of its residents and visitors.
