Dover has plenty of history that you can explore from a Roman house to the Castle high above the White Cliffs through to the 2nd World War.
The Tourist Information website is http://www.aboutbritain.com/towns/dover.asp
, and has links to all sorts of activities, hotels, Bed & Breakfasts, things to do (the list at the bottom, not the left) including animal parks, art museums, cinema, theatres etc.
Hope this helps,
