Yesterday, the news broke that Harlem is making a push for more historic districts. On Thursday, someone bought a One Museum Mile penthouse for $3.1 million. And there are still a couple of listings bordering Central Park with asks exceeding $5 million. It looks like Harlem is on the rise, and with that in mind, we present to you a small map of the higher-end open houses in Harlem this Saturday. One of them is in the same building (111 Central Park North) as one of the +$5 million listing. (All of them, however, have been lingering on the market for at least six months and have undergone multiple pricechops.)
