Chestnut Hill, Philadelphia, "Night of Lights" public history and art event
Via the Philadelphia Inquirer:
From October 9th-2th5, Chestnut Hill’s Germantown Avenue turns into an outdoor public art exhibit celebrating the area’s history and architecture.
Note that the Georgetown Business Improvement District in DC sponsors a similar kind of event in December and January called "Glow," focused on outdoor, lighted public art. It's equally cool, but doesn't specifically aim to promote local history as part of the exhibition.
Public art projections, public history projections, architectural lighting of buildings, church steeples (Cleveland has a program that assists churches in the cost of implementing and operating the ongoing lighting of steeples), etc., should be considered as part of neighborhood cultural history planning, public art planning, and community and commercial district activation planning.
