- The region of southeastern Pennsylvania where southern Berks, northern Chester, and eastern Lancaster counties meet is known locally as the "Tri-County" area. The Tri-County area was first settled by Welsh immigrants, and later by German, Irish, and Scottish immigrants. While the area was largely agricultural, it also developed into an important early industrial corridor. In the early twenty-first century, the Tri-County area is a mix of farmland, industry, and suburban real estate development. Tri-County Heritage Society local history collection, 1735-1990s, consists of manuscripts and other original materials, photographs and audiovisual materials, secondary-source materials, printed matter and ephemera, and other documents relating to the history, residents, organizations, and businesses of Berks, Chester, and Lancaster counties. There is also some material relating to Delaware, Montgomery, and other nearby counties in Pennsylvania.
