Transamerica Pyramid
From Memory Alpha, the free Star Trek reference.
The Transamerica Pyramid was a distinctive pyramid-shaped building in San Francisco on Earth.
The building was visible among the skyline in from the San Francisco Bay Stadium, even from the podium. (ENT: "Home", "Affliction")
Harry Kim and Libby's apartment was fairly close to the building, and had a clear view of it through their window before he was assigned to Voyager. (VOY: "Non Sequitur")
In 2376, it was one of the buildings in San Francisco recreated by Species 8472 in Terrasphere 8 for training to infiltrate Earth. It was depicted on a graphic Seven of Nine brought up in Astrometrics. (VOY: "In the Flesh")
