Bostonians celebrated Black-owned businesses Saturday in Nubian Square, sharing in a vision of Black ownership in Roxbury and reveling in the feeling of community.

The event, called “Buy the Block Party: Unity Day Edition,” aimed to combine the atmosphere of a party with the calculated strategy of advancing Black-owned businesses.

The event “honors the broader vision of economic self-sufficiency for Roxbury,” according to the Madison Park Development Corporation, one of the event’s sponsors, which is helping another sponsor, Black Market Nubian, to purchase their building on the block.
