Coit Tower was built in 1933 as part of a bequest left by Lillie Hitchcock Coit, a wealthy socialite who had a fascination with firefighting. She left one-third of her estate to the city of San Francisco, and the money was used to fund various public projects, including the construction of the tower. Due to its historical significance, unique architecture, and stunning views, Coit Tower is a must-visit landmark for anyone exploring San Francisco. Visitors can not only enjoy the art and architecture of the tower itself but also marvel at the panoramic vistas that stretch out from its observation deck.
