The Old Haa has a large collection of artefacts, some of which are on permanent display.
They are used as appropriate in seasonal history exhibitions, and you can find several of them on display throughout the museum.
There is a piano which is probably the oldest musical instrument in Shetland, and which was partly paid for by Sir Walter Scott when the owner was unable to meet the cost.
In the Archive there is an extensive sound archive and a photographic collection containing over 16,000 images including items from the Bobby Tulloch bequest and the Maxwell Bruce collection. There is also the Davie Arthur archive which contains glass plate negatives from the beginning of the last century, and a very worthwhile book collection.
All these can be accessed by prior arrangement with the trustees, who are also happy to assist with school projects and research activities.
