Possible landmark

The Citgo sign that lights up the Boston skyline and is seen by baseball fans when a home run balls sails over Fenway Park’s left-field wall has been granted preliminary landmark status.

The 3,600-square-foot sign in Kenmore Square features a red delta and the blue word “CITGO” on a white background. There was fear it could soon be gone because the six-story building on which it sits is part of a parcel of Boston University buildings for sale.

WHDH-TV reported the Boston Landmarks Commission granted preliminary landmark status to the Citgo sign Tuesday. The status means the sign can’t be changed or removed without the commission’s approval.

Further study will be done. The commission then would vote on whether to make the sign a landmark. The mayor and the City Council would have final say.
