345 California Center
San Francisco's fifth-tallest tower has a secret: the crown is a hotel, and it pivots 45 degrees from the shaft below.

Completed in 1986 at 695 ft, this financial-district tower was originally planned 98 ft taller and its top 11 floors were once drawn up as condominiums — they became the Four Seasons instead. The hotel occupies twin towers angled sharply away from the main building, linked by glass skybridges that frame views across the Bay Area. Historic buildings occupy every corner of the surrounding block.
What to look for
- Twin hotel towers at the summit rotated 45 degrees from the main shaft — visible from street level as the top of the building appears to break direction
- Glass skybridges connecting the upper floors, framing views of the San Francisco Bay Area
- Historic buildings at each of the four corners of the block the tower occupies
The Four Seasons hotel entrance is at 222 Sansome Street — a separate door from the office lobby address at 345 California.
