This panel considers the diverse cultural expressions of mosque design, past and present, in areas where Muslim populations are both minorities and majorities. It explains the history and reasons behind traditional gender segregation in mosques and how this segregation plays itself out in mosque architecture and affects ultimately the spiritual experience of the community. Panellists Dr Sam Bowker and Reem Sweid discuss the arabisation of mosques and the extent to which contemporary Australian approaches to 'sacred space' might offer a distinctive contribution to the wider Islamic global heritage.
