Angkor Wat is a huge temple complex (1.626 km²) in the region of Angkor in Cambodia.
It is assigned to the Khmer king Suryavarman II, built between 1113 – 1150 and dedicated to Vishnu. Since its rediscovery in 1860 many restoration work has been done to preserve this masterpiece of architecture. Angkor Wat is built out of around 5 million sandstone blocks with a weight up to 1,5t, transported from a quarry at least 40km away. The main temple complex is sourrounded by a moat ( 1,5km x 1,3km). The centerpiece consists of a temple with 5 towers representing a Quincunx. The main tower is 65m high and hides a secret. A 27m deep vertical shaft leads to a stone box. What was the purpose of this box? The midday sun shines exactly in this deep shaft. Furthermore there is an alignment to spring equinox, when the sun rises exactly over the central tower. Angkor Wat is huge, yet all the walls are beautifully decorated with carvings showing scenes of the Ramayana and Mahabharata. In the region of Angkor there are more than 1.000 temples but we still know so little about them.
