World's Second Tallest Building completed.

Dubai's Burj Khalifa still stands as the World's
Tallest Building.

Construction of the World's Second Tallest Skyscraper has been completed in China's Commercial City of Shanghai.

The final beam was hoisted to the top of the 632-meter Shanghai Tower on Saturday and was installed in a flag-waving ritual. 

After the ceremony, workers will now move on to the building's interior construction. Once it is completed next year, the tower will contain retail and office space, a luxury hotel and possibly a museum.

Designed by the American architectural firm Gensler, the glass and steel building is surpassed in height only by Dubai's Burj Khalifa, which stands closely at 830 meters.
