It’s magical to think that we are able to experience this piece of art dating VII century BC. Among thousands graves, at least 200 are decorated with a number of frescos which are the main core of the Etruscan art. On this site, you can visit around 22 tombs. Some of them are closed and the frescos are not so well maintained unluckily. Still, something to see once in life. Together with the necropolis of Cerveteri it is one of the most important archaeological sites of the Etruscan civilization. The price is 6 euros to visit the graves but I recommend to combine it with the visit to the Etruscan museum in the center of Tarquinia (unmissable!) for 10 euros. If you go during summer, bring water because you will have to descend in each grave (22 times down and up) and it gets pretty hot as you are outside under the sun or down the graves where there is no air conditioning. Good visit for families and groups. I advise to read a bit before the visit so you are better aware of the history of the place and the tombs. Toilets available on site.
