The coolest buildings used to have sharp angles and straight lines — but nowadays, a lot of the world's most beautiful structures are entirely round. Here are the most beautiful and impressive circular buildings of the 21st century.
The 25-floor Fang Yuan Building, an office building in Shenyang, China, completed in 2001.
The 33-floor (453 ft or 138 m tall) Guangzhou Circle in Guangzhou, Guangdong, China, designed by AM Projects Milan, built between 2010 and 2014. It's the new headquarters of the Guangdong Plastics Exchange, and looks remarkably like an antique Chinese copper coin.
