Millennium Tower, completed in 2009 in San Francisco’s financial district, was initially celebrated as a luxury residential skyscraper. However, it began sinking and tilting shortly after construction due to its foundation being built on deep concrete piles in sand rather than directly anchored into bedrock. By 2015, the tower had sunk nearly 16 inches and leaned noticeably toward the northwest. This alarming issue drew international attention, with comparisons to Italy’s Leaning Tower of Pisa. Legal disputes ensued as various stakeholders debated the cause of the sinking, with some blaming nearby construction and others pointing to the building's faulty foundation. Despite city officials assuring residents of its safety, a stabilization project commenced in 2020, aiming to anchor the building to bedrock 250 feet below ground. However, the repairs faced setbacks, including further tilting during construction. By 2023, the tilt had somewhat slowed, but the project remains a notable example of engineering challenges. The value of the apartments has significantly decreased, transforming what was once a premier residence into a symbol of engineering failure.
