Television Hill in Baltimore, transmitter site of 5 out of the 7 major tv stations serving Baltimore. Three transmit from the tri-mast candelabra tower (red color), WBAL, WMAR, WJZ. 2 transmit from the single tower just to the northeast, WBFF, WNUV, which i also think handles communications for the city of Baltimore (i.e. police, fire, public works).
Four of the stations are also physically located on TV Hill, WJZ to the west of the candelabra tower, WBAL to the northeast (also home of WBAL-AM and WIYY-FM) and WBFF/WNUV which share facilities in the black roofed building with the dishes on the roof just southwest of the candelabra tower.
