Buildings and landscapes rich with history abound in southeastern Pennsylvania, northern Delaware, and western New Jersey. As members of the Tri-State Coalition of Historic Places, we value these sites. They link us to those who lived here before us. They define our communities today. We are the staff members who commit to saving them and sharing their meanings with our neighbors, near and far.

Tri-State Coalition of Historic Places developed in the early 1990s from conversations between historic site administrators in the Philadelphia region and staff at the Pew Charitable Trusts. Members researched and published Standards and Practices for Historic Site Administration, now in its second edition. See the order form on the Resources page of this website.

Tri-State Coalition of Historic Places offered  a collaborative marketing project, Story Tours, from 2004 until 2006. In recent years, we focused on small to mid-sized historic sites, offering networking and professional development opportunities. In 2009, we launched a website, with the help of members of the University of Delaware’s Communications Department.

Join Tri-State Coalition of Historic Places! Become a part of a network of history professionals dedicated to telling the story of our region, through its buildings and landscapes.
