Don't Forget to Call Your Mother! – H Street and 21st Street N.W., Washington D.C

When they were replaced in the 1970’s by the new 911 system, the ornate, wrought-iron emergency call boxes that still grace the streets of the District were an unwanted remnant of old infrastructure. Too heavy and burdensome to remove, they became increasingly derelict until many of them were weird windows on the city. Devoid of any mechanism or purpose, they were like faceless clocks, or little streetside shrines with no idols inside. Since 2002, however, the "Art on Call" project, created by Cultural Tourism D.C., has turned 122 of the 1860s-era fire and police call boxes into public pedestals for local art and quirky history markers.
