Located in the Financial District on Montgomery Street, standing at 850 feet tall, this 40-year-old building is visible from many parts of the city. Viewed from the street below, its window pattern makes it look like a giant cheese grater. The Pyramid is not open to the public and can only be appreciated from the outside or via a 4-camera virtual observation deck in the lobby. Around the structure’s base are several curious plaques and memorials. A small park beside it on Clay Street offers interesting outdoor perspectives for photographs.
