My home town is Galle. I did my studies there. When we were in Galle, we had a habit of going to Fort in the evening. With higher studies and job, I was out of this for a long time.
Last weekend I had time to visit the Galle Fort in the evening and see the sunset.
It's really a wonderful view to see. My recommendation is to plan your trips or visits (if you are going on that way) to be on the Galle Fort in the evening, to watch the sunset.
