The Secrets of Rome #2 [hint][solution]

In the Black Hole puzzle someone said he visited Rome but never saw that place.
Well, that's a challenge! I will make a new series of unusual places in Rome.

For every thread you will have to guess 3 places, I will divide them in difficulty levels: easy, medium and hard. Have fun!

Easy: Barche [street view]



Medium: Tunnel Vision [blue dot]



Hard: The Cellar [blue dot]

 

Thanks for this nice challenge. I was very pleased with it . I visited Rome in the past as well, and also didn't visit these unusual places, and didn't visit 'the black hole'. So, time for a revisit.
