Okay, That's Very Hydra

177A Bleecker Street, New York City

Located in Lower Manhattan, this street was lined with many old buildings. Among them stood a mysterious structure with a huge circular window—the Seal of the Vishanti. This was the former New York Sanctum.

Mr. Hulk and Hawkeye found the Ancient One. Though she had not intervened to stop the Battle of New York, she stood atop the building, casually dealing with any Chitauri that attacked this area.
