When Did Hostile Architecture Start?

The origin of the term is unknown, but hostile architecture has always been part of urban life. In 19th-century England, anti-urination devices—conical mounds of stone filling out the corners of buildings—prevented people from relieving themselves.

Why does hostile architecture exist?

Hostile architecture, otherwise known as anti-homeless architecture, is a form of architectural design to prevent or impede crime and help maintain order. The strategy uses the built environment to discourage malcontents from using public spaces for activities that they were not intended to be used for.

When did defensive architecture start?

Consistent with the widespread implementation of defensible space guidelines in the 1970s, most implementations of CPTED as of 2004 were based solely upon the theory that the proper design and effective use of the built environment can reduce crime, reduce fear of crime, and improve quality of life.
