I quote from the Wikipedia: "The Villa [Giuglia] was built by the popes and remained their property until 1870 when, in the wake of the Risorgimento and the demise of the Papal States, it became the property of the Kingdom of Italy. The Museum was founded in 1889 as part of the same nationalistic movement, with the aim of collecting together all the pre-Roman antiquities of Latium, southern Etruria and Umbria belonging to the Etruscan and Faliscan civilizations, and has been housed in the villa since the beginning of the 20th century." And: [It houses the National Etruscan Museum.] The museum's most famous single treasure is the terracotta funerary monument, the almost life-size Bride and Groom (the so-called Sarcofago degli Sposi) reclining as if they were at a dinner party."

You can see many pictures of the latter in this gallery, as well as other things I enjoyed. I had to scan and edit slides, some have been edited differently from others, since they stem from different visits, using different film (and the museum may have changed background colour, light conditions and so forth). From some I had to bleed almost all colours, others look alright.
