Step into a time machine and explore the Flatiron and Gramercy neighbourhoods as a traveller from 2520. This self-guided puzzle adventure takes you through 15 stops across some of New York's most fascinating hidden history.

Your mission: test a portable time travel device by pointing it at landmarks and jumping between centuries. Decode messages at a Prohibition-era tavern, unravel a mystery at Manhattan's only private park, and witness a shocking crime at the original Madison Square Garden.

Discover stories most tourists never hear: a grave in the middle of Broadway, three buildings that were each the world's tallest, and a president whose glasses kept getting stolen.

The route covers 3.5 km from Union Square to Madison Square Park with audio at every stop. Best during daylight. Start anytime and play at your own pace.

Great for couples, families, and history lovers. Download the Questo app, enter your booking code, and head to Union Square to begin.
