city wall
Town's defensive perimeter
A city wall is a fortification enclosing a town or city, built for defense against invaders.
Ancient and medieval cities typically had walls with gates controlling entry and exit: The old city wall still stands in parts of Jerusalem.
City walls became obsolete with modern artillery, though many survive as historical monuments.
