Since 1916, the National Park Service has been entrusted with the care of our national parks. With the help of volunteers and partners, we safeguard these special places and share their stories with more than 275 million visitors every year. But our work doesn’t stop there.
We are proud that tribes, local governments, nonprofit organizations, businesses, and individual citizens ask for our help in revitalizing their communities, preserving local history, celebrating local heritage, and creating close to home opportunities for kids and families to get outside, be active, and have fun.
Taking care of the national parks and helping Americans take care of their communities is a job we love, and we need—and welcome—your help and support.
The National Park Service preserves unimpaired the natural and cultural resources and values of the National Park System for the enjoyment, education, and inspiration of this and future generations. The Park Service cooperates with partners to extend the benefits of natural and cultural resource conservation and outdoor recreation throughout this country and the world.

Sacred Spaces – A Place for Reflection in the Past and Today
Earthen mounds and embankments forming huge geometric enclosures grace the landscape of the Ohio River Valley. These monumental structures were built by Native American hands almost 2,000 years ago. Hopewellian people gathered at these earthworks for feasts, funerals and rites of passage. Come learn about these sacred spaces and reflect upon the lives of these American Indians.
