Like National Historic Sites, National Historical Parks preserve an aspect or area of America's diverse history. While Historic Sites usually focus on individual properties, Historical Parks encompass multiple themes or a large tract of territory, sometimes across several states. Under the National Historical Parks umbrella, an entire downtown area such as Boston or the area around Philadelphia's Independence Hall might be designated, incorporating centuries of history.
