Wow, what a treasure. I haven't been to this part of Rome and didn't have enough time, to be honest, to discover such a historical treasure. I must admit this is not a typical castle. Seeing the era and timeline of the castle, I must admit it is still in good shape. Buying tickets online is always handy; I have made the same mistake and had to wait long to enter Pantheon...
Thanks for sharing...
Rome is amazing and even though I was there for 5 days (4 nights), I didn't manage to see everything I wanted to see, but there is still something to do next time, of course, apart from Rome, I have a few more cities I want to visit.
Indeed this castle is still in a very good condition considering its age, anyway Rome is a history book ready to be discovered, I can't wait to write a few more posts with my experiences in Rome.
Have a wonderful weekend!
