For one summer evening, the working shipyard around the ICA Watershed in East Boston turns into a neighborhood block party. It’s completely free with no tickets required — live music, art-making tables, lawn games, face painting, and booths from Eastie community organizations fill the yard on Marginal Street, with food available for purchase.

The vibe is genuinely local: this is the ICA throwing a party for the neighborhood that hosts its harborside outpost, and East Boston shows up. It suits families with kids in tow, art people who want an excuse to catch the Watershed’s current show, and anyone happy to spend a golden-hour evening by the water. The Blue Line to Maverick, then a short walk through the neighborhood, is the easy way in.
