The site at Pompei is extensive and takes at least half a day to explore. The granary shows plaster casts of victims of the eruption, their expressions especially impressive after hearing the stories on the news about the South Asian tsunami disaster. Just like those victims, these ancient Pompeians had no chance.
I've seen quite a lot of ancient excavations, but due to the special circumstances under which it was preserved this one is really special. The feeling of the town as a whole has survived: not only the major buildings but also the streets, the normal houses and the restaurants. Take for example the ubiquitous Thermopolia, where snacks could be bought. You can just imagine having a quick lunch there yourself.
The rich preferred to build their villas just outside the town, overlooking the sea. One of these is the Villa of Mysteries. Here I sheltered from a hailstorm. The villa is decorated with several extremely beautiful and well preserved/restored frescoes. The dining room in the front has a large painting of a woman's initiation to marriage. Elsewhere there are delicate Egyptian motifs waiting to be admired.
