How can I view "archived" Google Chrome history — i.e. history older than three months?

You can open them using SQLite Database Browser or one of the many other programs that can open SQLite databases.

Solution 2:

I think this is no longer possible

My old answer

Download ChromeHistoryView (freeware). Click "Options > Advanced Options". Point the tool to the location of your Archived History file.

The tool is made for Windows.

If you don't have access to a Windows PC, that's okay. I've found that it works fine in Wine, so you can also use it on Mac and Linux.
