Public Art Ribbon Cutting Celebration, Mareas by Ana Teresa Fernández

On January 15, 2026, we celebrated the unveiling of Mareas by Ana Teresa Fernández, a new permanent public artwork arch at Pier 27’s James R. Herman Cruise Terminal Plaza along San Francisco’s Embarcadero waterfront.

Mareas, Spanish for “tides,” was created to reflect the shifting patterns of light, color, and movement across the San Francisco Bay. Standing over 13 feet tall, the sculpture is constructed from steel and polycarbonate resin, with architectural resin materials by 3Form, and fabricated by One Hat One Hand. As daylight changes, the surface catches and refracts light, casting a wave of blue across the plaza that evolves throughout the day.

Positioned at the pedestrian entrance to Pier 27, Mareas acts as a gateway—welcoming visitors arriving on foot, by transit, or by car, and anchoring the space between the Bay, the city skyline, and the cruise terminal. Its flowing form echoes the motion of water while offering a bold counterpoint to the surrounding architecture.

The dedication unfolded under open skies with friends, collaborators, and community gathered along the waterfront. Now a permanent fixture on the Bay’s edge, Mareas responds to tides, light, and weather—inviting anyone passing through to pause, look up, and experience the Bay in motion.
