While working in architecture, Charles Rennie Mackintosh developed his own style: a contrast between strong right angles and floral-inspired decorative motifs with subtle curves (for example, the Mackintosh Rose motif), along with some references to traditional Scottish architecture. The project that helped make his international reputation was the Glasgow School of Art (1897–1909). During the early stages of the Glasgow School of Art Mackintosh also completed the Queen's Cross Church project in Maryhill, Glasgow. This is considered to be one of Mackintosh's most mysterious projects. It is the only church by the Glasgow-born artist to be built and is now the Charles Rennie Mackintosh Society headquarters.
