Borobudur, a Buddhist temple built a bit more than a millenia ago in central Java near Yogyakarta, is a UNESCO world heritage site and a massive tourist attraction, so of course I had to go take a look.
Much like Prambanan, Borobudur was forgotten and “lost” from records a couple of centuries after it was built, and remained hidden in the jungle growth for centuries, until it was re-discovered along with Prambanan by an explorer commissioned by Sir Raffles (is there anything he can’t do?). And now, like Prambanan, archaeologists are working to restore the temple.
