This is a small compound with the most prominent item being the part of the pagoda (3 levels at the base standing, out of possible 7 or 9 levels based on the width of the base). You can see this as a part of the overall Gyeongju visit but not a whole lot to see in this laid-back temple. You...
Bunhwangsa is just 20-30min walk from the museum and shows a beautiful central temple remainder. Next to it is a small buddhist temple which you'll be able to enter - typical very relaxed atmosphere in there.
The pagoda here is nice and the hall that remains has a good statue in it, but, in all honesty, it is not worth the price or the journey. I run a website dedicated to temples and I visited the temple so as to have a complete picture of Gyeongju.
