For centuries alleys have been one of the classical elements of shaping and outfitting open space as well as the cultural landscape and urban space. The problem of their preservation and, in particular, cultivation with due respect for the principles of conservation is, however, a relatively new topic. Due to the multiple different forms and arrangements which comprise an important and constant feature of forming gardens and garden interiors, the question of cultivating avenues calls for intensive conservation attention. Material gathered by the Working Group of Conservators of Historical Gardens at the Union of German National Conservators presents a wide range of conservation problems and possibilities, demonstrating with the assistance of assorted example the available princples of preservation, cultivation and repair. The presented publication is to assist conservation praxis.
