There are beautiful halls inside the castle. The floor in them is lined with mosaic marble of several types. Very beautiful! If you take a photo next to the sculpture of the Holy Angel on the observation deck above, it will seem that you are under his protection and he is driving away invisible enemies with a huge sword.
Of course, a must-visit place in Rome. Unfortunately, the bar is closed, and you will not be able to drink an aperol with a view of the Vatican. But this does not beg for the need to visit a place that is 1,889 years old.
