Shaar Hanitzutz - Gate of Sparks

In front of this gate was a small courtyard surrounded by columns, which
supported a balcony upon which Kohanim from the priestly guard stayed
watch at night.

The sun's rays shining between the columns appeared to be flickering sparks, giving the gate its name.

The gate was also called Gate if Yoachim, because it was from this very spot that King Yoachim was led into exile by Nebuchadnezzar toward the end of the First Temple era.
