Essex is a community built just outside the Eastern border of Baltimore City and has plenty of development along Eastern Avenue. During the 1940's and 1950's, the Alert Theatre was listed as the theatre in the 500 block of Eastern Avenue, seating between 285 and 350 people. By the 1951, another theatre was listed for Essex at 416 Eastern Avenue, going under the name of the New Essex Theatre, and seating 625 - listed until atleast 1957.  The building is no longer a movie theatre, and apparently suffered a fire back in the 1950's., and was either rebuilt or greatly altered. Back in the early 1930's, The Electric Theatre was listed for Essex ( Address unknown ) , which seated 320. By the late 1930's, that theatre was going under the name of the Elektra. I have no idea at this point if that was indeed the Alert  Theatre.

.....Above, 416 Eastern Avenue - Could this building be the New Essex Theatre ? From what I have been hearing , it is not, as the old theatre burned down.
