Gravity Falls Library

The Gravity Falls Library was the town of Gravity Falls' resource for books.

History
During Pioneer Day, Dipper and Mabel went there to search for information on the true founder of Gravity Falls. There, Dipper found that the symbol on the map hidden in the book 3 was the alchemical symbol for flame, and decided to burn it accordingly. However, before he could do so, Mabel folded into a hat, inadvertently making a map.
