Custom House was once the beating heart of London’s port operations, and though it no longer handles customs, it now stands as a living museum of maritime history. This grand Neoclassical building, with its imposing columns and intricate carvings, still commands attention from the riverfront. Step inside to explore exhibits tracing Britain’s seafaring legacy, or simply sit on the steps watching the Thames cruise by—time slows down here, letting you relive the pulse of a bygone era.
