Phyllis Lyon and Del Martin bought the cottage in 1955
It soon became a meeting place and refuge for local lesbians
The couple founded the Daughters of Bilitis, a political and social organization for lesbians, and wrote books and magazines about lesbian rights
They became the first to get married in 2004, when then-mayor Gavin Newsom wanted to challenge the state's ban on same-sex marriages
They were married again four years later, when the Supreme Court struck down the state's ban
Lyon died in April 2020, and the house was left to Martin's daughter
She sold it for $2.25 million, but local activists wanted to save it
