The final date in this series is 2011. The museum had been closed for some time to allow an extensive refurbishment to take place and it reopened again in mid 2011.
The new part of the building is in contrast to the traditional Bath stone of the rest of the building. Ceramic tiles, glass and metal form fins and very geometric shapes at the back of the building. It is the colours and lines of this part of the building that inform the fourth purse.
The design of the purse is a simple rectangle with a zip at the top.
