Whitstable Museum and Gallery is a heritage centre in Whitstable, Kent, and is notable for its displays showing the history of the local oyster trade started by the Romans and of historical diving equipment. It is open on Thursdays to Sundays in summer, 11:00am to 4:30pm. Admission is free for locals and £3:00 for visitors, with access for the disabled.
The present museum was established in 1985. The museum received the Nautiek Award, for services to diving history, in 2001; the first time the award had been given to a UK establishment.  A recent Arts Council grant has enabled the museum to be repainted, with new lighting and a general facelift.
The building is like the Tardis in that the tiny doorway opens up into a large hall of displays. In 1881 the Ancient Order of Foresters bought the building, and inscribed "Foresters' Hall" over the door.
The natural world display shows life on the shoreline, including plants, fossils, sealife and birds.
The museum's largest object is Whitstable's first horse-drawn fire pump, which was manned by twenty-six volunteers. In 1867 the Norwich Union Fire Insurance Society had donated it to the town. The diving display shows Standard diving dress with Siebe Gormanhelmet and the traditional red bonnet to protect the head against the helmet (see image below). The museum also contains relics from the East IndiamanHindostan, which wrecked at Margate in January 1803.
The collection includes ship paintings on the theme of international and local trading links; town, shore and coastal views; the work of local artists; artworks borrowed from an international network of galleries.
There are about six exhibitions per year: some local, some which have toured nationally, and some with associated public events. In 2001 there was a special exhibition about art and water. In March 2002 there was an exhibition in which visitors could handle historic diving equipment and watch films about diving. There was a 2009−2010 exhibition on the last oysteryawl, Favourite, and a Girl Guides exhibition in 2010, finishing in March. The museum takes part in the annual Whitstable Oyster Festival by hosting interactive exhibitions. In September 2009, the museum had a World War II frontline exhibition.
Workshops are provided for schools and colleges, and students can study with practising artists. Adult courses, and a children's "Little Oysters Story Time" are held in addition. In 2007 there was a workshop in which children could make sock animals.
