JW Marriott San Francisco Union Square, 21-story hotel in Union Square, San Francisco, United States
The JW Marriott San Francisco Union Square is a brick building in downtown San Francisco with 329 guest rooms and suites arranged around a central core. A 17-story atrium with a central fireplace runs through the middle of the structure, bringing natural light into the interior spaces.
Architect John C. Portman Jr. designed the building in 1986, combining modern design with functional urban architecture. Its completion marked an important addition to downtown San Francisco's hotel offerings during a period of urban renewal.
The building displays works by local artists in its common areas, reflecting San Francisco's creative community. This collection shapes how the space feels and connects visitors with the city's artistic traditions.
The property includes extensive meeting facilities such as a conference center, ballroom, and multiple function rooms for business and social events. The central atrium provides clear orientation for guests and easy access to dining options and services throughout the building.
The impressive 17-story atrium floods the interior with daylight, creating an unexpected open space within the dense urban surroundings. This design feature offers guests a rare experience of calm and brightness in the heart of the busy downtown area.
