Tarquinia is a town in Lazio, Italy. At first site it looks like a miniature version of San Gimignano with its medieval towers but the main reason for visiting is that it has fascinating Etruscan tombs with wall paintings (UNESCO World Heritage Site), as well as a good museum on the Etruscans.
At first sight, you may well be disappointed. You only see a barren piece of land with what look like workers' huts on a building site. However, each covers a set of steps going down to a tomb and you can turn on a light to see through the glass. Each tomb has a painting. Some are well preserved: others less so but when you consider that the paintings are 2500+ years old it is quite an amazing experience. Some of the better wall paintings have been removed to museums; if you cannot get to Tarquinia do not miss Rome's Etruscan Museum at Villa Giulia (Rome/North_Center)
A little hard to find but the pasta is worth it. It's a local Italian restaurant. You'll sit alongside tables of old Italians and young workers. The menu has a kitschy illustration and the pasta is made al dente. The seafood is a specialty of the region and is also very good.
