Sponsored by TOWN Residential and Look Up New York.

This week, TOWN kicks off the second month of Look Up New York, a three-month-long interactive photography project celebrating the architectural gems of New York City that we often overlook in our everyday routines. Over the past four weeks, Look Up New York has highlighted such iconic buildings as the Woolworth, the Frick Museum, the Chelsea Hotel and the Flatiron Building (which, if you didn’t know, once was known as “Burnham’s Folly”).

Presenting readers with the overarching challenge, “Think You Know Your TOWN?”, Look Up New York unveils an iconic black-and-white, museum-quality image of architectural detail from a notable New York building each day for 90 days, along with a briefing on the address’ lesser-known history. Readers will find the complete library of timeless photography at LookUpNY.com.

To date, more than 2,200 Instagramers have contributed their own photography with the hashtag #LookUpNY. Visit LookUpNY.com to view the complete Instagram gallery, as well as a borough-wide map of submissions in real-time.

TOWN invites you to post your favorite NYC architecture on Instagram with the hashtag #LookUpNY for the chance to have your photo and profile published on a full page of New York Magazine. Good luck, and don’t forget to #LookUpNY!
