Grotta

This artificial cave looks like something out of a fairytale. 

Looking like something straight out of a fairytale, Grotta is unusual artificial cave with arcade promenade in Prague. Built by millionaire Moritz Gröbe between 1871 and 1888, Grotta was opened to the public from 2011 after a renovation.
