This text is unique in bringing together a number of scholarly perspectives in the arts and humanities to examine how spatial and architectural design decisions convey meaning, shape or abet specific social practices, and stage memories of frontier zones that no longer function as such. With studies from Asia, Africa, the Middle East, Europe, and North America, this collection of essays casts a wide net to consider borders of diverse sorts. This range allows for reflection on shifts in how frontier zones are articulated and the impermanence of border emplacements, as well as on likely scenarios for future frontiers.
