Unfortunately, ThinkQuest has been discontinued as of 1st July 2013. However, their data has been archived, most of which should be available from the ThinkQuest Library.

I recently found this website, though unfortunately the data is not free. It is also available from Stanford University, on the off-chance you're in some way affiliated with them or know someone who is. https://www.euratlas.net/shop/maps_gis/gis_1600.html
