Ghirardelli Square (adaptive reuse of chocolate factory)

Ghirardelli Square preserves the brick factory buildings of the original Ghirardelli Chocolate Company and was transformed in 1964 into a public square with shops and restaurants. Its conversion is widely cited as an early and influential example of adaptive reuse in the United States, retaining historic industrial fabric while accommodating new commercial uses. The complex remains a prominent example of preserving industrial architecture within an urban waterfront setting.
