I was currently just doing some research on roman forts in Britain and i came across this site that gives u virtual tours and tons of details about
I did Classical Studies in high school for 6yrs and just mad about discoveries and archaeological sites.
The sites spans the whole of the UK and deals with places like:
Carmathen bay and its shipwrecks
The Clay Hill 1999 excavation
Creswell Crag - Home of the Ice Age hunter
Its worth a look as it is a brilliant Information Archive.
Have a good day
