It's not the most impressive castle I've ever seen, but castles are always worth a look. This one, I read, is the largest castle complex in the world.
There are several ticket options available, each of which grants you access to different parts of the complex. Option A is full access, and is, of course, the most expensive. We went with Option B, which granted us access to the castle and to Golden Lane, which is a giant waste of time altogether.
All captions in the castle were in Czech. Basically, we just wandered through a few rooms wondering what it all meant. Then we went in the tower to check out some torture devices, but you get more and better explanations at the torture museum in Prague, which you should definitely visit.
Golden Lane is just a bunch of shops with goods you can find in the market or elsewhere in town. It seems silly that you need a ticket to get in there. You'd think they'd want you to go there so you will buy things.
The views of the city, of course, are fantastic, as they are at pretty much any castle. We were there for the changing of the guard, which is always interesting, I think. It's such a simple little switch, but so formal. I think there must be great pride in such a job, even though it must be fairly miserable, just standing there all day, not moving, in very cold weather.
They also had a cool nativity scene in front of the cathedral. I was very impressed.
They do have a picture gallery, but our ticket did not allow us to see it.
Hmm. Basically, if you've never seen a castle before, check it out. Climb up there to see the city. But if you've been to the Tower of London or the castles in Edinburgh or Krakow, you will do fine to skip this.
