Wow! The displays and how it is set up is amazing. Because it is the Crown Jewels, there is more security than other museums. You cannot bring anything in, there are lockers next door to put all your stuff. After going through security, you literally enter a massive vault. You take the elevator down and explore a beautiful collection of the Portuguese royal family. The history and collection are beautiful. The set up is well done, we really enjoyed the table placement and the graphics that accompany it and how the mirrors allow you to see all sides. As you descend the levels they have pictures of the royals through the years. It is very worth a stop and takes approximately one hour, you could maybe do it a little quicker. There is a cafe at the end, we did't try anything but it is there if you want something! read more
