On the same night than the next picture I went up 북한산 (Bukhan Mountain), high enough to get to 승가사 (Seungga Temple). This temple has a huge Buddha and a big pagoda. This pagoda faces the city (Seoul), that explains the light behind it, and unfortunately it is surronded by trees so I couldn't help but having them in my shot. I also used my head light to illuminate it, that explains the weird lightning!!!
