while digging for a McDonalds building’s foundation in Frattocchie, Italy in 2014, workers found about 150 feet of an ancient Roman road, constructed between the second and first centuries BCE.

The McDonalds was then part of the excavation, preservation, and built the restaurant a storey above the road, with some glass floor areas so diners can look down at the 2000 year old road, or head down the stairs to get a close up look. Yes, 3 skeletons were found, recreated with fakes, and relocated. 

This makes it the only McDonalds with a museum. 

And the only one not able to use a preexisting road for a drive thru
