I highly recommend visiting if you are in Naples. Stunning interiors, especially the central white marble staircase! And, very importantly, in the sultry summer, the air conditioning works in the palace and you can escape from the scorching heat outside!
The Royal Palace of the Kingdom of Naples. It will be interesting for those who are interested in interiors, architecture and design. The palace has residential, ceremonial royal apartments, there is a court theater (not to be confused with the San Carlo Theater, it is located in this building, but this is another theater), a basilica, a throne room, etc. The palace impresses with the beauty of its doors, each of which was painted by artists and did not repeat its drawing! The visit will take no more than 40 minutes, there is a terrace with a garden, but they are not allowed there. There are few people, so you can come, buy a ticket quietly and visit the palace. The ticket price is 10 euros.
