The link for the location of the ancient city wall was wrong. We followed the link to the city hall, but couldn't find it after walking around. Finally, we saw the church tower across the bridge and walked over. We walked up the path through the church and saw the ancient city wall. But it took 20 minutes to walk along the road beside the city wall to reach the entrance. The correct address should be: Carrer dels Alemanys, 20, 17004 Girona. You can drive up and there is a parking lot. Or another entrance is Carrer General Marvà, 1, 17004 Girona, Spain. No tickets are required.
