Built in 1420, the Temple of Heaven was where Ming (1368-1644) and Qing (1644-1911) dynasty emperors worshipped heaven for good harvests. It was turned into a public park in 1918.

The 600-year-old monument covers an area of 270 hectares and is considered one of the largest existing architectural complexes in the world.

Just as the original circular building is completely wooden with no nails, the Egyptian radiologist used only matchsticks, white glue and a cutter blade to build the replica of the temple.

"Even the unapparent supports and structures are all made of matchsticks," he notes.
