About
Milford Haven Museum sits beside the Old Custom House on the waterfront of Milford Haven, a Pembrokeshire town with an unusually distinctive origin story: unlike most historic Welsh ports, Milford Haven was founded as a deliberately planned settlement in the 1790s by Sir William Hamilton, inheriting the estate through his marriage to Emma Hamilton's predecessor, and developed with the involvement of Quaker whaling families from Nantucket who were invited to establish a whaling industry exploiting the deep, sheltered natural harbour of the Milford Haven waterway, one of the finest natural anchorages in the British Isles.
The museum's displays trace this unusual planned-town origin and the town's subsequent whaling era, when Nantucket whaling families brought their specialised knowledge and equipment to found a British whaling fleet operating from the new harbour, before the industry's decline in the face of competition and changing markets during the early nineteenth century. The town's economy subsequently shifted towards fishing, and Milford Haven became, for a period in the late nineteenth and early twentieth centuries, one of the most important fishing ports in Wales, with a substantial trawler fleet and associated fish processing and ice-making industries supporting a large local workforce.
The museum's most significant later chapter concerns the twentieth-century transformation of Milford Haven into a major oil refining and terminal town, as the deep natural harbour that had once sheltered whaling ships and trawlers proved equally suited to the vast crude oil tankers of the post-war era. From the 1960s, several major oil refineries and terminals were established around the waterway, fundamentally reshaping the town's economy, employment, and skyline, and the museum documents this industrial transformation alongside its earlier whaling and fishing history, giving visitors a picture of a single deep-water harbour supporting three quite different maritime industries across two and a half centuries.
As a small, community-supported local history museum, Milford Haven Museum relies on volunteer effort to maintain its displays and welcomes visitors keen to understand this distinctive planned town's unusual transition from whaling settlement to fishing port to major energy terminal.

Highlights
A Planned Town Founded by Whalers
The museum's founding exhibition explains Milford Haven's distinctive origin as a deliberately planned settlement established in the 1790s, when the estate's owner invited Quaker whaling families from Nantucket, Massachusetts, to relocate and establish a British whaling fleet exploiting the deep, sheltered natural harbour of the Milford Haven waterway.
Displays document the practical and religious motivations of these American Quaker whaling families and the layout of the new town they helped establish, making Milford Haven one of the few British towns with such a direct and well-documented American colonial connection to its founding.
The Whaling Era
The museum documents the town's short-lived but historically significant whaling industry, exploring the specialised equipment, ships, and expertise the Nantucket families brought with them, and the products — principally whale oil for lighting and industrial uses — that the fleet produced during its operational decades before increasing competition and changing markets led to the whaling industry's decline in the early nineteenth century, after which many Nantucket-descended families remained in Milford Haven and diversified into other trades.
Milford Haven's Trawler Fishing Fleet
Following the whaling era's decline, Milford Haven developed into one of Wales' most important fishing ports, and the museum's displays trace the growth of its trawler fleet through the late nineteenth and into the twentieth century, along with the associated ice-making, fish processing, and market infrastructure that supported a substantial local fishing industry workforce at its peak, before national trends of declining fish stocks and changing fishing industry economics reduced the fleet's scale in the later twentieth century.
The Oil Refining Era
The museum documents the transformation of Milford Haven from the 1960s onwards into a major oil refining and terminal town, as the same deep natural harbour that had sheltered whaling ships and trawlers proved ideally suited to the large crude oil tankers of the modern energy industry.
Displays explain how the establishment of major refineries and terminals around the waterway reshaped the town's economy, employment structure, and skyline, connecting Milford Haven's history directly to the story of Britain's post-war energy industry.
Collections
The museum's collections span Milford Haven's unusual sequence of maritime industries, from whaling equipment and documents relating to the town's Nantucket Quaker founders, through fishing industry photographs, models, and equipment from its trawler fleet era, to material documenting the twentieth-century oil refining and terminal development that transformed the town's modern economy.
The Old Custom House building itself, part of the historic waterfront infrastructure, forms an integral part of the visitor experience alongside the object and photographic collections.
