Named after the ancient Greek muse of history, Clio puts history at your fingertips. With your permission, Clio picks up your present location and guides you to landmarks, museums, and historic sites. It also acts as a virtual time machine, allowing a user to see images and videos and hear and read about historic events that happened around them. We are adding new features including interactive walking/driving tours and push notifications coming soon.

Because Clio is free, it depends upon people like you who care about history and culture. If you would like to help, please send us an email at We are working to provide new features like push notifications and interactive walking tours thanks to donations and other forms of support. The Clio Foundation is recognized as a public charity under IRS code 501c3 and all donations are tax deductible.

With several hundred new entries and improvements being added each month, Clio is not only a website and smartphone application, but also a collaborative research, interpretation, and map-building project. Museum professionals, scholars, and their students contribute most of Clio’s content. We also depend upon local history experts and museum volunteers who often know more about local history than anyone else. Each day, this partnership of local history experts and professional historians is building a comprehensive, dynamic, and interactive map of American history.

Incredible Gateway to History


I’ve started to discover history all around me that I couldn’t believe was there. When I’m visiting a new place for the first time, this is the kind of stuff I’m looking for—it’s just so nice to have it all in a one-stop shop (figuratively, since Clio is free and non-profit).

Since discovering Clio, I’ve become a regular contributor. The platform keeps getting better as more and more knowledgeable folks contribute. The Tour creation feature is especially amazing. Sure, the UI could be snazzier, but it’s absolutely the best platform out there for discovering history everywhere you go. Keep it up, Clio!

Excited to have this app


I read an article about Clio on Facebook and was impressed with their website. Searching my area brought up locations I've never been - even though they are less than 30 miles away. Now that I know more about the history, I want to visit these places in person. (Feels like that was the objective - way to go Clio!) Excited to have this app.

So very handy


I heard about this App from a friend that uses this when she travels for work and wants to learn about the area. I gave it a try on a recent trip to Philadelphia and absolutely LOVED all of the interactive maps and history I learned about this wonderful city! I will definitely be using this again in the future when traveling to new places!!
