CRGIS is a map-based inventory of the historic and archaeological sites and surveys stored in the files of the Bureau for Historic Preservation (BHP).  To get started, follow one of the login options in the left navigation bar: New User Login or Returning User Login.

The Pennsylvania Historical and Museum Commission (PHMC) has been collecting information concerning archaeological sites and historic resources for the greater part of a century. Currently there are approximatley 20,900 archaeological sites and 128,500 historic properties in these files. Access to these paper records is free and open to the public by appointment at the BHP office in Harrisburg. CRGIS is a means of accessing some of these data without a trip to Harrisburg.

Web access to all of the historic resource data is open to the public. Access to archaeological site locations and detailed site information is restricted and password protected and will be granted to qualified individuals on a need to know basis. Two levels of restricted access are available: one for planning professionals and one for archaeological professionals. Visit the Register section of our Web site to register for a password.  The "Ask ReGIS" function will allow you to query the underlying databases in a variety of ways to look for sites that are of interest to you.

CRGIS is an ongoing initiative, and tables and associated data will undergo staged enhancements and constant updating. Users are encouraged to notify CRGIS about additions or corrections that may be needed by using the "Feedback" function of the "Ask ReGIS" page. Please include references or other documentation for changes or additions. New sites will be added when received. Please refer to our Recording Resources section for more information on submitting resources for inclusion in the CRGIS.

CRGIS is a partnership between the Pennsylvania Historical & Museum Commission (PHMC) and PennDOT, with financial support from the Federal Highway Administration, the Baltimore District of the Army Corp of Engineers, and the Pennsylvania Department of Environmental Protection.
