This Buddhist Temple is 능원사 (Neungwonsa/Neungwon Temple) inside the entrance to 도봉산 (Dobongsan/Mt. Dobong) park. Very close to 도봉사 (Dobongsa/Dobong Buddhist Temple). The 단청 (Dahncheong) colors are now bright with gold. I visited in 2007 when there was only fresh wood.
You are an expert to find bright autumn colors at 남산 (Mt. Namsan)!
Wow! Unbelievable how may locks are on that fence now! I must visit again.
