Baltimore Sun publisher and editor-in-chief Trif Alatzas informed Sun employees today of the sale of what’s been their headquarters for 66 years this way:

“Tribune Real Estate, a division of Tribune Media, has informed us that it intends today to put The Baltimore Sun’s Calvert Street building up for sale.

“Since the spin-off of Tribune Publishing in 2014, we have been leasing our Calvert Street space from Tribune Media. A sale would not impact our current lease agreement to continue occupying the building.

“Thank you and keep up the great work.”

Two years ago, Tribune Media Co. sold The Sun’s printing plant in Port Covington for $46 million to Sagamore Development, the real estate firm owned by Under Armour’s CEO Kevin Plank. The Sun is leasing the building back from Sagamore.
