I watched a show about Pompeii several weeks ago. It is amazing what they have been able to find. I like ancient history.
Herculaneum is less well known, and I don’t think much of it is open to tourists. Partly that’s due to the fact that its remains lie under the modern Ercolano; partly it’s due to the fact that the town was covered in pyroclastic flow, and the poison gas is released when the solidified rock is dug out of the ruins, making excavation risky.
But there’s an old Michael Grant book I have around here, uh, somewhere, that covers all the towns to some extent, and Herculaneum’s destruction led to phenomena such as, there are wood doors carbonized by the heat, found in situ, and they still swing on their hinges.
