We were cleared into the Alleyway to proceed to the gate from ramp control. As one taxis in; that gate is on your right. Unknown to us; at a gate (on our left); a B747 had taxied in sometime before us. However; they did not taxi the entire way into the gate. They had stopped short of the gate; and were in the process of being towed in by a tug the rest of the way. We were cleared into our gate by ramp control. As we were clearing the area to our right; I saw a blue flash in my peripheral vision to the left -- and saw the right winglet of the 747 dangerously close to our left side. I told the Captain to 'STOP' which he did abruptly. A wing-walker/marshaller was also giving the stop sign. It seemed like the B747 tug team pushed their aircraft backwards during their tow-in. If we had continued straight ahead; our left wing would have gone under the B747 wing by several feet.  When we queried ramp; the controller only said; Yeah; they usually take forever to tow-in that B747. We were cleared in by this same ramp controller -- never apprised of the tow-in in progress.
A319 First Officer reports a near collision with a B747 during taxi into an alley gate. The B747 was under tow into a gate on the opposite side of the alley and may have been pushed back slightly. Ramp Control did not mention that the B747 was under tow.
