Filming the impressive church Sagrada Familia – this was the plan. I placed my YI 4K Action cam on an appropriate bezel which I stuck on a Zhiyun gimbal. I started on the west entrance, walked through into the big hall and went a whole round. Although many tourists were inside, I got a good impression of this one-of-a-kind building. Inside was heavy construction work, the structure of this great church continues and will last until 2026.
