Henry VIII ordered the Mary Rose early in his reign, and the ship entered royal service in 1511. Built principally of oak, she combined sailing power with an increasingly heavy gun armament during a period when English warships were becoming specialized artillery platforms. The vessel served in campaigns against France and Scotland, underwent major rebuilding during the 1530s, carried soldiers as well as sailors, and embodied the crown's investment in a permanent navy. Her surviving objects also reveal archery, navigation, carpentry, medicine, food, clothing, music, and everyday labor aboard a Tudor warship.

On 19 July 1545 the Mary Rose sailed from Portsmouth during a French attack on the Solent. She turned, heeled sharply, took water through open gunports, and sank within sight of Henry VIII. Most of those aboard died, though the precise number and the chain of causes remain debated. The starboard side settled into oxygen-poor silt, which protected part of the hull and thousands of objects while exposed portions decayed. Tudor salvagers recovered guns, rigging, and other material, but the wreck gradually disappeared from practical memory beneath changing sediments.

Divers located the wreck again in the nineteenth century, and Alexander McKee's twentieth-century search led to its confirmed rediscovery in 1971. Archaeologists excavated the seabed as a carefully recorded site rather than simply hunting valuables. On 11 October 1982 engineers raised the surviving hull in a purpose-designed cradle during a globally watched operation. More than nineteen thousand recovered artifacts and human and animal remains created an unusually detailed record of shipboard society. Research has continued to revise assumptions about the crew's origins, health, skills, diet, and the ship's construction and loss.

Only a large portion of the starboard hull survives; the museum does not present a complete original ship. Conservators reattached hundreds of loose timbers where structurally possible, supported the remains with modern steelwork, and continuously sprayed the wood after raising. Polyethylene glycol treatment ran from 1994 to 2013, followed by controlled drying and preventive conservation. Galleries suggest the missing port side through architecture, projections, lighting, and displayed objects. These interpretive elements are modern, while the dark, fragmented timber mass is authentic sixteenth-century material profoundly altered and stabilized by burial and conservation.

The Mary Rose Trust operates the purpose-built museum within Portsmouth Historic Dockyard and continues monitoring humidity, movement, chemistry, pests, and structural loads. Admission, access, and conservation arrangements can change, and the hull remains an active scientific project rather than a finished relic. Interpretation should distinguish the ship's Tudor service from its modern archaeological afterlife and avoid presenting disputed sinking explanations as settled. The museum's power comes from placing original timbers, personal possessions, weapons, and human evidence together while making the extensive recovery equipment, chemical treatment, reconstruction, and digital visualization visible parts of the story.
