There are some new articles on Etrusia’s Roman history site. http://romans.etrusia.co.uk/roman_pompeii.php is a brief introduction to Pompeii and Herculaneum, with links to some 30 year-old photographs of parts of Pompeii that may not all be accessible to a visitor today.
There is also a short article on Hadrian’s Wall, on the same principles – a basic background introduction to the Roman monument that stretches across the whole of the North of England, with many sites along the route which will interest visitors. http://romans.etrusia.co.uk/roman_hadrians_wall.php
More shameless plugging, I guess.
