We spent a wonderful 3 hours here and ended the day at Bakong Temple. The Red Sandstone Tower of Shenniu Temple is beautiful and Bakong Temple is majestic. It was one of the highlights of our 3-day temple tour and would definitely recommend. The Rollos group is the site of the first capital city of the Khmer Empire and we are honored to visit this historic site. The driver told us that the temple was built in the 9th century and is older than Angkor Wat.
