Two Vietnamese artists Giang Quoc Co and Giang Quoc Nghiep have broken Guinness World Record by climbing 90 stairs in 52 seconds with one sibling balancing atop the other using only their heads.

“The brothers chose to carry out their amazing feat on the picturesque steps of the Cathedral of Girona in Spain, made famous as one of the locations where the popular TV series Game Of Thrones was filmed”, said Straits Times of Singapore.

The brothers, among the most renowned circus artists of Vietnam, are known for their performance Suc Manh Doi Tay (Power of the Arms), in which they perform various technically-demanding stunts using their arms and hands. The performance won a Silver Bear prize at the 2012 International Circus Festival in IZHEVSK, Russia.

They also were invited to attend the 2013 Monte Carlo International Circus Festival in France.
