The Maclaurin Trust was founded as a bequest from the late Mrs Mary Ellen Maclaurin, who, in her Will, provided that curators appointed within the Will should, within five years of her death, build an art gallery / museum in Ayr to be called The Maclaurin Art Gallery in memory of her husband.
Premises were identified at Rozelle House and the Trust was granted a tenancy of the east wing of Rozelle House and curators were given powers to upkeep the art gallery and to purchase pictures and other exhibits.
The Trust has built up one of the best collections of 20th, and now 21st, century art in the country, part of which collection is exhibited from time to time and is lent to other galleries. The gallery also provides hanging space for various local art groups and attracts exhibitions from far and wide.
