The pyramid-shaped penthouse atop Seattle’s oldest skyscraper is officially on the market for the first time ever. Built in 1914, Smith Tower was originally the first skyscraper in the city and tallest building west of the Mississippi River at the time. The glass globe that sits on the very top of the structure is also accessible through a spiral staircase if you truly want to reach the highest point of the building.
I like the idea of this better than the reality of the apartment. The thought of a secret sanctuary, overlooking the whole city, is a cool worldbuilding element.
