It's an abandoned building that became a viewpoint and popular meeting spot. People hang out here admiring the panoramic view and having snacks. The building itself is raw and unfinished with plenty of murals and art.
Panwa Viewpoint looks like a nice spot although it got a bit cloudy and wet once we reached the top so unfortunately we couldn't see whole panorama. The way is nice though and what we were able to see was still nice.
