While in Jave recently, we stayed in Jogjakarta for four nights. Spent a few hours at Candi Prambanan. Candi means "temple." Borobudur is Candi Borobudur. Most impressive. It's Hindu 9th century and really big. The bottom picture gives an idea of size with people in it though there's a temporary fence in that one that wasn't there when we were there.
