While we were in Prague we did three separate tours for three separate reasons. We were pretty disappointed With this tour as we booked this one specifically to learn about “alchemy and mysteries of Prague castle”. Really the only thing that matched the description was that we did go to Prague castle. I’m not sure if maybe the Tour guide didn’t realize which tour they were doing because we just learned about a lot of history of Prague (which was covered in another tour we took earlier that day). Throughout the three hour tour we didn’t really touch on any mysteries or alchemy at all. Since this was a paid tour we were pretty disappointed with the outcome since we already paid for this information earlier the same day.
