There's a second name bolted above hundreds of NYC street signs. It can be an activist, a musician, a doctor, a firefighter, a neighbor. Know Your Block is a walking companion for those names. FIND THEM ON THE MAP A map of New York shows every honorary street sign in the collection including 289 icons across Brooklyn, Manhattan, Queens, the Bronx, and Staten Island, from Christopher "Notorious B.I.G." Wallace Way to Elizabeth Jennings Place. Filter by category: civil rights, music, arts, public service, and more. READ THEIR STORIES Every icon has a story page: who they were, what they did, and why their block carries their name (curated from NYC Council co-naming records and public sources). A century before Rosa Parks, Elizabeth Jennings held onto a streetcar window frame near this stretch of Lower Manhattan; her lawyer later became President. BUILT FOR WALKING - Optional nearby notifications, generated entirely on your device - Your progress never leaves your phone: no accounts, no ads, no analytics - Location is used only while the app is open, and never stored or transmitted Know Your Block is an independent project and is not affiliated with the City of New York or any honoree's estate.
