Rolls Group and Collapse Mile belong to the same direction and are far away from buildings such as Angkor, so it's better to arrange a car rental all day. On this day, you can take one of Carmen's "May Blossom" or "Travel through Cambodia and Angkor Temple all over the world" without a tour guide, hold a book, walk slowly, take a close look at every building, fine-grained sculptures in every corner, and sit in the ruins of the past to feel the brilliance of art. Rolls Group is located about 15 kilometers southeast of Siem Reap City, by the existing Temple of Bagong Temple. Bakong, Temple of Preah Ko, Temple of Lolei. All three temples were built at the end of the 9th century. They were the earliest buildings in the Angkor era lasting about 600 years. They were called Beginning of Classic Period of Khmer Art. They all use the same building structure, carving materials and construction methods.
