These photographs of Angkor Vat (sic), Angkor Thom, and some of the smaller Cambodian temples show the difference between the overgrown ruins of 1912 and today’s domesticated tourist attraction. Guide aux Ruines d’Angkor by Jean Commaille contains many more photos plus maps of the grounds and plans of the temple construction. The depredations of the jungle would eventually have destroyed everything but I still prefer to see the walls and statues festooned with foliage.
