Diving Museum

The Diving Museum is currently closed for improvement works that started in November 2023. The work will include ramp access from the outside of the building to the front door and a lift at the entrance that will enable visitors who cannot manage the stairs to safely arrive and leave the building. When the work is completed, No. 2 Battery will have an attractive new frontage with ramp, steps and newly planted shrubs. At the same time, some internal work will be undertaken to attempt to resolve the damp issues that are so common with Victorian buildings of this nature. An opening date in 2024 to be advised later.

Gosport is the home of the global diving industry. The co-inventor of the diving helmet, John Deane, lived in Gosport from 1835 to 1845 during which time he discovered the Mary Rose. The first diving helmet ever sold by the inventors was to a Gosport mariner, Henry Abbinett. Gosport represents a natural home for the country’s premier historical diving museum.

The Historical Diving Society museum was established in No.2 Battery at Stokes Bay  in August 2010. It opened to the public on 30 April 2011 and was formally opened on 18 June 2011 by the Mayor of Gosport, Councillor Chris Carter in the presence of Caroline Dinenage MP and Vice Admiral Sir Richard Ibbotson CB DSC.

The Museum houses a collection of exhibits and artefacts connected with the history of diving. The Historical Diving Society (HDS) was formed in 1990 in the UK by a group of enthusiasts whose aim is to preserve and protect diving heritage.

On display at the Gosport Hiustoric Diving Museum is the Deane Helmet. This is classed as a National Treasure. It is the world’s first successful diving helmet and dates from the early 1820s. The Historic Diving Society are extremely proud to have it in their museum in Gosport, on loan from The Science Museum, as this is the first time it has ever been on display.
