It is a beautiful sight of Zagreb. The people who are selling the tickets are so bored so at some point you don’t want to go up there. I bought the ticket for 3 Euros 💶 and went upstairs. At some stage you think that there won’t be an open area but at the end there is and you can see Zagreb in 360 degrees.

This tower is located right at the top of the funicular between lower and upper parts of Zagreb. We didn't get the chance to go inside it, but we were there in the courtyard below it for the daily noon firing of the cannon from its top. This was a fun experience - and startlingly loud, even if you're expecting it! We were told the name means "Burglars' Tower" and that it was part of the defense of the city during the Middle Ages.

Set your watches and watch your ears. People of Zagreb have set their watches by the cannon blast at 12 midday since the middle of the 19th century. Just watch your ears though as its bloody loud. We found this out when sitting on the funicular below. I knew it was going off but didn't realize it was 140Db. It scared the heck out of my wife and others on the funicular which was actually funny to see. It costs 3 Euros each to enter and has a narrow winding staircase to reach the top which was a fairly easy climb. It had amazing views of Zagreb and was a great price. Other towers in Europe we had climbed had cost a lot more. You can see the cannon when climbing the stairs and as it had just been fired, you could still smell the cordite in the air. If you're in the tower when it goes off, make sure you cover your ears as it is 140 Db. This was a great experience and well worth the money and time to get awesome views over Zagreb.
