Narrative:

We arrived on time into ZZZ. While being towed into parking; I felt that we were too close to the fence on my side. (Right). I advised the captain to stop the pull. He immediately told the ground crew to stop the pull. They advised him that they had a wing walker and we were clear. They continued to pull the aircraft. I felt very sure that this was unsafe and for a second time announced; stop the pull; we are not going to clear the fence. The captain once again stopped the ground crew immediately. This time a large group of people walked to the right side of the airplane and spent several minutes looking at the clearance. I could see that we had almost hit the fence pole; but until seeing the pics that a ground crew took; I didn't realize that we drove over the pole. Missing it by approximately 12 inches. The wing tip was about 2 feet past the pole.ZZZ was not ready for a 777 to arrive. We were pulled into the wrong spot that was designed for a 767. We found out later that our spot was changed due to a 747 coming at the last minute. The ground crew over rode the captain's authority and assured us that we were clear.better training for the ground crew involved. That spot is not suitable for a 777. Although I was very assertive; next time I will refuse to allow the airplane to put in jeopardy with me in the seat. I felt as a crew; we handled the situation well; but I also felt that we were not totally in charge of the push crew. Next time I feel I don't have a safe distance; I will contact the chief pilot for further guidance.
