Petrin tower is one of the landmarks in Prague. It was built in 1891 and is actually a copy of the Eiffel tower with ratio 1:5. It is 58.7 meters high and is already situated on a hill. On a clear day, you can actually see almost all of the Bohemia region in Czechia.
Of course, they love to take your money there for comfort. The general ticket was 6 eur and if you want to use the lift, it's another 6eur, otherwise, walk the stairs up.
Views were definitely beautiful in every direction you look. Below you can see the pictures I took in the tower to every direction.
The park around the tower was also really nice to walk in. I didn't take many photos there but here are a couple of these I have.
