This is the old tomb that was just discovered in Cerveteri and then unveiled to the public in 2003. There are so many tombs and ruins under the ground here they don't even know where to begin to dig.
In the second photo up you can see the sea on the horizon. The old Etruscan port and coastline is now under water, but you can see how they built their tombs up from the shoreline as seen here.
The bottom photo is of the popular fountain in Cerveteri. As nice as their Etruscan museum is, the collections at Rome's Villa Giulia and the Musei Vaticani are both better. At the British Museum in London they even have Cerveteri rooms. However, the tombs are worth a visit if you have a rental car.
