The Great Hall in the National Gallery of Victoria was opened on August 20, 1968. Its magnificent ceiling is the world's largest stained-glass ceiling, designed by Australian artist Leonard French. The ceiling is high (13.72 metres), vast (60.9 x 15.24 metres) and so heavy with glass and steel that its downward projecting triangles need to be held up by a series of slim steel columns. Each of the main intersecting triangles has been turned into thousands of geometric pieces of coloured and clear glass that have been cut so their facets bounce and refract coloured light. The 224 triangles of diamond-cut primary colours weigh 300 kilograms each.
