The former Custom House is an eighteenth century rubble-stone building of two storeys under a hipped slate roof, with a projecting central gabled wing of three storeys and attic. It currently houses the Milford Haven Museum, where displays, prints, photographs, documents and paintings illustrate the history and development of the port and town, including the modern oil terminal.
