Salesforce Tower is an unmistakable giant, topping out at 1,070 feet tall -- more than 200 feet taller than the Transamerica Pyramid, the previous tallest building in San Francisco.
It's also nearly 300 feet taller than the Bank of America building.

Groundbreaking for the tower began in 2013. Timelapse video shows the building as it grew over the past five years. It became known as the Salesforce Tower in 2014 after the cloud computing company signed a lease to become the building's main tenant.
The skyscraper, a symbol of the ascension of the tech industry, represents 28 percent of the city's workforce.
Workers installed the tower's trademark 11,000 LED lights as part of an art installation that will light up nightly, featuring moving images from photos taken around the city.
