Really great museum that is different from any other museum I've been to so gave it the 5 stars. Not the best most extensive museum but unique. The history was really cool although very specific to a window of time. I appreciated being able to see something so old yet so well preserved it was like traveling back in time. The exhibit got you up close to all the showings so you could see the detail that went into keeping this hidden church maintained and well...hidden. It is deceptively takes a while to complete the whole tour since it seems so small. The included audio tour really made it worth the money since there was a lot that needed explanation. From start to finish it was about an hour give or take. We were able to take as many photos as we wanted which is sometimes prohibited in other museums. I would definitely recommend this site especially if you have already done the standand Amsterdamn museums (Anne Frank, History Museum, canal tour, etc) or if you want to experience something a little different. If religion is absolutely not your thing then maybe pass on this. They dont make you pray or get baptized but if you dont have a sense of religious appreciation then this museum would be lost on you.
