Download CENTENNIA

The Centennia Historical Atlas software runs under Apple Macintosh OS X (macos 10.5 or above), as well as Microsoft Windows (Windows 10, 8, 7, etc.). The app requires 20 megabytes of disk space. Centennia does not have any other significant system requirements, and it will run well on almost any computer manufactured in the past ten years.

The files available for download here include all text and map data covering ten centuries of European and Mid East history. The French Revolutionary and Napoleonic Period (1789-1819) is available at no cost. To access the full time period, all ten centuries from 1000 AD to the present, you will need to purchase an access code.

Download Centennia for Windows: Download Centennia for Windows.
The Windows download (fully compatible with Windows 10/8/7 etc.) is a zip file containing the Centennia Windows Setup program. Download it, open it, then double-click "Centennia Windows Setup" to install.

Download Centennia for Macintosh: Download Centennia for Macintosh OS X.
The Macintosh OS X download is a disk image (dmg) file. Download it, then drag the Centennia app to your computer's desktop or hard disk. Double-click to run.

Note for Mac users: If you get a security warning saying Centennia can't be opened, right-click or ctrl-click on the file and then select Open from the sub-menu. You'll see a dialog saying Centennia is from an unidentified developer. Are you sure you want to open it?. Click Open, and you're all set. This is normal.
