A group of fearless teens have filmed themselves performing nail-biting stunts at the top of a 600ft TV tower - with no safety equipment.

Daredevil Ervin Punkar, 17, risked life and limb to scale the Tartu TV mast, built in 1857, with his two best friends, Keivo Pint, 19 and Jüri Uluots, 17.

It took the intrepid trio an hour to reach the summit, where they performed death-defying stunts above the sprawling landscape of Tartu - the second largest city of Estonia.

Braving the stomach-churning drops, the teens, from Tartu, use a GroPro attached to a selfie stick to capture themselves dangling from ledges and balancing on top of tiny platforms.

While one wrong move could mean certain death, the thrill-seeking friends had been planning the climb for months, as they were determined to capture views of their home city like never before.

Ervin, a filmmaker and photographer, said: 'We mostly wanted to climb the tower because it seemed like a great challenge and an amazing experience.

'The view from up there just beats everything, it's so beautiful.

'Getting there was really cool actually - it took us about one hour to reach the top, but we made many stops to rest and simply enjoy the view.

'Although it wasn't the first time we've climbed the tower, we wanted to capture it all on film to show how amazing it really was.'

To gain access to the tower, the trio had to sneak past CCTV cameras and motion sensors, or risk being caught by the security on site.

Seemingly unfazed by the dazzling heights, the teens described the climb as 'really safe actually', despite having to scale the first section of the mast without the help of a ladder.

Ervin said: 'I didn't feel my life in danger at all, even when we were on top doing these 'crazy stunts'.

'It's all about knowing and trusting your body and its capabilities.

'Under the tower there were a lot of cameras and motion sensors, so we had to sneak past all of these, which got us really hyped and prepared for the climb.

'The way to the first ladder was blocked, so we had to climb to the first level from the middle, which was really uncomfortable, because there were no bars.

'I can't even explain how it was exactly, but I can say that that part was the most risky and dangerous for me.

'It's not really different from hanging off from a tree at ground level for example.

'The only difference is in your head; physically you're doing the same thing.'

Ervin has been scaling tall buildings since he was 14, but puts his extreme confidence when climbing down to his training in parkour.

He said: 'When I climb these building I feel at peace with myself - I'm totally in the moment and really feeling good about myself.

'Of course it's a little scary, but that is what makes it interesting.'
