Water is a defining feature of Westminster's geography and urban planning.
* **The River Thames:** Forms the entire southern boundary of the borough. The Victoria Embankment runs along the river, offering sweeping views of the London Eye and the South Bank. * **The Serpentine:** A large recreational lake created in the 18th century in Hyde Park, dividing it from Kensington Gardens (where it becomes known as The Long Water). * **The Canals:** The northern part of the borough features the convergence of the Grand Union Canal and the Regent's Canal at a picturesque basin known as Little Venice, characterized by colorful narrowboats, waterside cafes, and tree-lined towpaths.
