The Shanghai Tower is a megatall skyscraper in China, standing at 632 meters tall with 128 stories. It's the tallest building in China and the third-tallest in the world. Designed by Gensler, it's known for its sustainable features and tiered construction. Construction started in 2008 and was completed in 2014, with the tower opening to the public in 2015. It boasts the world's fastest elevators and offers stunning views from its observation decks. The tower faced challenges attracting tenants initially but has since seen increased occupancy rates, including housing a luxury hotel on its top floors.
