HISTORICAL FORTIFICATIONS IN THE ARCHITECTURAL AND URBAN PLANNING STRUCTURE OF LVIV (ON MARGINES DOCUMENTATION "HISTORICAL AND ARCHITECTURAL REFERENCE PLAN OF LVIV")
Ancient city fortifications are one of the specific types of defensive architecture. Along with the buildings of castles, blocks of urban residential development, monastery complexes and field defensive structures, they formed a special type of architectural and urban planning objects. During their construction, the skills of both an architect, builder, and military engineer were often combined. Not so many objects of urban defense architecture have come down to our time.
