South Korean construction workers were shocked when the building they were working on suddenly started to tilt.
The building is now leaning at a 20 degree angle, which is a 5 times greater tilt than the famous landmark, the Leaning Tower of Pisa.
No one knows what caused the building to suddenly tilt and luckily no one was hurt during the incident. Construction is still underway to complete the building.
