The Collections comprise some 25,000 items, ranging from steam locomotives to fine art, and including local archaeology, ceramics, textiles and costume, natural history specimens, as well as objects illustrating domestic, working and community life. Of particular importance are the Cornish Beam Engine at Prestongrange Museum, the Haddington Weavers and Craighall Friendly Society banners and a collection of stone anchors.

Collections not on display are held in our environmentally-controlled store at the Museums Service Headquarters in Haddington.
