At 121 feet in height, the fearsome Excalibur in the Netherlands is the world’s tallest freestanding climbing wall. The concrete climbing tower has a dizzying 36 foot overhang and a 500 ton foundation to keep it from toppling over. It is the centerpiece of Climbing Centre Bjoeks in the outskirts of Groningen. For more photos see this photos set by photographer Eric Kieboom.
At Bjoeks Climb Center, there is an array of indoor climbing walls, including one designed for first-timers and another that’s at a 45 degree angle. There’s also a large indoor-outdoor bordering area with 117 boulders to scamper over.
As long as you don’t take into consideration mountains, cliffs or other man-made structures not specifically designed for climbing. The curved design results in sections that are easy for beginners to tackle, as well as some extremely difficult parts where experienced climbers will literally find themselves hanging.
