The Tenement Museum on Orchard Street reveals the fascinating reality of how immigrant families lived in NYC's overcrowded tenements during the early 1900s. It's compelling social history that tourists overlook while rushing between food tours and Instagram spots.

The guided tours take you through meticulously restored apartments, telling authentic stories of Irish, German, Italian, and Eastern European families who called these cramped spaces home. You must book tours in advance as they're limited to small groups for preservation reasons.

Combine your visit with a walk through the neighborhood to witness how dramatically it's transformed. Many original tenement buildings still stand, now converted to expensive apartments. The historical irony isn't lost on current residents paying $3,000 for spaces that once housed entire families.
