The North End’s iconic pizza shop is one 12 Regina’s Pizzeria affected by Boston Restaurants Associates Inc.’s bankruptcy declaration in federal court on Wednesday.

The famous brick oven pizza joint’s board of directors voted to authorize the bankruptcy filing in April, according to The Boston Globe. They have moved to close four underperforming stores and are trying to renegotiate three heavy leases where business has declined.

Regina’s opened in the North End in 1926 and has been a landmark for authentic pizza seekers ever since. They have 19 locations throughout New England, two of which are owned by Polcari’s Italian Restaurant in Saugus and Woburn.

There is one in Allston and in Foxwoods Casino in Connecticut that operates with the Regina’s name, but are owned by two different companies. These locations are not affected by the filing.

Boston Restaurants Associates have between $1 and $10 million in debts and assets and 490 employees.
