Located in the geographic heart of downtown, the newly transformed City Hall Plaza is Boston’s premier open-air event space. Following a massive $95 million renovation, the plaza now features a "plug-and-play" infrastructure specifically designed for large-scale music festivals. Spanning seven acres of accessible brick and greenery, the venue offers 10,000–12,000 capacity on the main plaza alone, with a total site capacity of up to 25,000. With its "Kinder Brutalist" backdrop, new shaded seating for 3,000, and a dedicated Civic Pavilion with full amenities, the plaza provides a modern, inclusive, and high-energy atmosphere for the Mojo Boston Music Festival.
