Archtober turns October into a citywide open door: AIANY boat tours along the waterfront, vertical tours up into the Cathedral of St. John the Divine, a Prospect Park walk on how its waterways were made, and a Building of the Day at the New York Historical's Tang Wing. The 2026 theme, In Our Hands, leans into handcraft, resilient structures and climate. If you like seeing the city from the inside, pick one tour this weekend and build a day around it.
What to expect
There is no single gate. You browse the Archtober calendar, register for individual tours, talks or workshops, then meet at each partner site. Formats range from walking and boat tours to hybrid talks, and self-guided options live on the Bloomberg Connects app and the Archtober map.

- Some tours, including certain Building of the Day visits, are not wheelchair accessible; check each listing.
- Wear comfortable shoes; many programs are walking tours or involve stairs.
