One of the most amazing places I have ever visited! Fascinating, Historical, Important, Scary, mysterious, intriguing and impressive.
It was easy to book on-line on the web a few days before our visit.
I recommend this.
The entry kiosk is very small and you have to look closely to see the entry door.
Amazing architectural engineering. The member of staff who led our tour was passionate and informative. (The tour is given in Spanish, and the guide kindly interpreted a little into English for us, as Spanish is not our first language). It starts with a video, and there are English subtitles on the video.
You must see this place, Hopefully it helps us all think carefully about preserving peace in our lives.
