Sigiriya, the ancient rock fortress and palace complex, is one of the most spectacular sights in Asia. Built in the 5th century, the rock is adorned with frescoes of celestial maidens painted on its western face, a mirror wall inscribed with ancient graffiti, and the Lion Gate at the base of the final ascent. The summit reveals the foundations of a palace and offers 360-degree views across the scrub jungles of the Cultural Triangle. Sigiriya is a UNESCO World Heritage Site and a memorable human achievement that leaves every visitor in awe.
