Since 1994, architecture, preservation, and urban design students and faculty from the United States and abroad have participated in summer workshops addressing postwar reconstruction of Mostar, a city in Bosnia-Herzegovina. This is an account of five summers' experience of a project intended to continue until the historic center is rebuilt and the divided city restored to multicultural unity. This account examines academic approaches to a complex environment far from the university, the processes of learning within a multifaceted and ongoing project, and the frustrations, accomplishments, and educational benefits of an ambitious international collaboration.
