Hang Seng Bank Tower, Modern skyscraper in Lujiazui, Shanghai, China

Hang Seng Bank Tower is a 46-storey, 203.4-metre skyscraper at 101 Yincheng Middle Road in Lujiazui, Pudong, Shanghai. Completed in 1999, it was originally the Sen Mao International Building and served as HSBC's mainland headquarters from 2000 to 2010. Hang Seng Bank (China) bought HSBC's floors for 510 million yuan in 2010 and moved in during the first quarter of 2011.

The tower was originally named Shanghai Sen Mao International Building and served as HSBC's main office until the bank relocated its headquarters in 2010. This shift reflected changing priorities in the region's banking sector and the building's transition to new management.

The tower shaped how Shanghai developed as a major financial hub and shows the role of international banking institutions in the city's growth. It stands as a visible marker of China's economic development and integration into global markets.

The building has 14 elevators distributed across its levels to move visitors and workers efficiently through the structure. Access and opening times may vary depending on business operations, so checking ahead is advisable before visiting.

HSBC bought floors 34 to 36, a ground-floor shop and the naming rights from developer Mori Building for US$33 million, which is why the tower carried the HSBC name until 2010. Hang Seng Bank (China) then paid RMB 510 million for those floors, approved in November 2010.
