To celebrate its bicentennial, this weekend the town of Pollena Trocchia opens its cultural heritage sites to the public. This is a great opportunity to visit the post-79 Roman villa with baths and other sites which might be of particular appeal if you're interested also in Classical Reception and Volcanology. Among the wonders, there are a Roman column base in the local church, an 18th century "Roman ruin" (but with a real Roman altar) in a Neapolitan nobleman's villa, and Vesuvius' small volcanic vents (you can actually enter into one of them!).
Some of this evidence has been published already, but there is more to explore.
I have created a page with directions to the archaeological site (or you can use Google Maps).
If currently you're not in the Bay of Naples, please get in touch with me and I'll arrange a visit for you (it might be nice to see us in action, from the 13th of June to the 15th of July).
