Eastern State Penitentiary

We'll visit Eastern State Penitentiary and do the self guided audio tour.

From their website:
Eastern State Penitentiary was once the most famous and expensive prison in the world, but stands today in ruin, a haunting world of crumbling cellblocks and empty guard towers. Known for its grand architecture and strict discipline, this was the world's first true "penitentiary," a prison designed to inspire penitence, or true regret, in the hearts of prisoners. Its vaulted, sky-lit cells held nearly 85,000 people over its long history, including bank robber "Slick Willie" Sutton and "Scarface" Al Capone.

Tickets are $21 for adults with discounts for seniors and students. Please buy your tickets before the event online at https://ticketing.easternstate.org/events Tickets may be sold out if you wait until the day of the meetup. Please be sure to purchase tickets for the Daytime Admission - Self-Guided Audio Tour

Also on their website: Since most of the historic site is not climate controlled and has limited running water, we recommend checking the forecast on the day of your visit to prepare appropriately for the weather. This includes dressing for comfort and bringing or purchasing bottled water. Sandals, flip-flops, open-toed shoes and high heels are strongly discouraged.
