From 1936-1939,
the Main Signal Station
of the Hagana - Israel’s pre-State army - operated on the roof of this building (once the tallest in the city).
Using lanterns at night and heliographs during the day, the station maintained communications with many Jewish towns and villages.

The sign is rectangular but its head is designed according to the emblem of the city of Tel Aviv
