Liverpool ONE is a shopping, residential, and leisure complex in Liverpool, England. The project involved the redevelopment of 42 acres of land in the city centre. It is a retail-led development anchored by the department store John Lewis. Debenhams had previously been an anchor tenant until the closure of its Liverpool One store in March 2021, with Marks & Spencer taking its place in mid-2023. Additional elements include leisure facilities, apartments, offices, public open spaces, restaurants, and transport improvements. The completion of Liverpool ONE significantly boosted the local economy, while lifting Liverpool into the top five most popular retail destinations in the UK.

The Old Dock, originally known as Thomas Steers' dock, was the world's first commercial wet dock. The 3+1⁄2 acres (1.4 ha) dock was built on the River Mersey in Liverpool, England, starting in 1710 and completed in 1716. A natural tidal pool off the River Mersey, which probably gave its name to Liverpool centuries earlier, was partially filled and locked in from the river with quay walls erected.
