Mount Stuart Trust was founded in 1989 by John Crichton Stuart, Marquess of Bute (1933-1993), with the aim of entrusting the historic Mount Stuart together with the land and resources previously comprising the Bute Estate to a charitable trust governed by a board of trustees. The trust is committed to conservation, environmental sustainability, innovation, public access, and education. Mount Stuart, House and Gardens, have been open to the public since 1995. Mount Stuart Trust is a charity whose aims, and objectives, are outlined in the Memorandum and Articles of Association.
