Building Stones Collection

The John Watson Building Stones Collection is named after John Watson (1842-1918), who donated his collection of approximately 300 British and foreign stones and specimens illustrating the manufacture of plasters and cements to the Museum in 1905. Watson had retired from his work in the Portland Cement industry and continued to develop the collection until his death in 1918. Today it comprises approximately 2,500 traditional building stones, roofing slates, road stones, flagstones and decorative and ornamental stones that were in extensive use throughout Britain and it's colonies during the 19th and early 20th centuries.

The collection is housed in the former Museum of Economic Geology in the Department of Earth Sciences. The collection is open to the public by appointment only.

Temporarily closed due to Covid-19
The government recently announced that museums and galleries will be able to re-open from 4 July. Here at the Sedgwick, we are really looking forward to welcoming you back, and are working hard to put in place plans to make sure visitors, staff and volunteers will be safe.  We anticipate that we will reopen later in the summer, and will involve a free, timed, ticketing system. We keep you informed of our plans via our website and social media. 
In the meantime, we are delighted that the Cambridge University Botanic Garden has already reopened
