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 more than 2,500 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).
The Monterozzi necropolis is an Etruscan necropolis on a hill east of Tarquinia in Lazio, Italy. The necropolis has about 6,000 graves, the oldest of which dates to the 7th century BC. About 200 of the tomb chambers are decorated with frescos.

It is said to be the best Etruscan museum in Italy outside Rome.
