- Swansea Museum is the oldest museum in Wales. The collections contain all kinds of objects from the past of Swansea, Wales and the rest of the world. We have everything from an Egyptian mummy to a Welsh Kitchen, displayed in six galleries. There are also many changing temporary exhibitions each year. It is a fascinating treasure house of Swansea's past history. The Museum building was completed in 1841 in the grand style of Neo-Classical architecture. The museum is architecturally significant, and it has been listed as a Grade Two * Building. The Museum has an extensive local history library that is open to the public by appointment. Please contact the Museum in advance of your visit to ensure that you can use the research facilities.
