In my thesis I argue that historic carceral heritage facilities should be preserved because they represent early 20th century histories of first wave feminists and working class Queer women. To do this I present the history of Lincoln Heights Jail, a 96 -year-old jail in Los Angeles, California and its associated women's history which has been underacknowledged. Then I analyze additional U.S carceral heritage sites associated with women.  Through my research I found most women's carceral heritage is intangible and so the preservation field needs to prioritize saving the remaining physical sites.
