After the Second World War, the impetus for a new beginning came in 1949 with the bequest from Robert Lillie, a banker and enthusiastic amateur artist, for the building of a gallery in Milngavie where Milngavie Art Club was to be permitted exhibitions within the Gallery. It was opened in 1962 with a selection of paintings on loan from Glasgow Art Galleries, along with works by Robert Lillie and a small exhibition of 28 paintings by 13 members of the club, among them Helen Carrick Anderson, Jean Irwin and Flora Wood. Famous artists such as William and Mary Armour and Joan Eardley were past members of the club.
Today more than 700 works are contained in the collection, including paintings, drawings, prints, mixed media, sculpture, ceramics, glass and textiles.
