Shaolin

This Holy Site is identical to a Native Trade Site. Allying with Natives allows a player to train special Native units, usually warriors, and also grants access to a group of improvements to that tribe. Native units do not cost any population spaces, but can only be built in limited numbers. One of the most famous Buddhist monasteries is the Shaolin Monastery, located in the Henan province of China, founded in 495 CE. The edifice is associated specifically with Chan Buddhism and the martial art of Kung Fu. Monastery legend states that the Indian monk Bodhidharma visited the temple in 527 CE. During his time meditating on the mountain overlooking the monastery, Bodhidharma taught himself a form of martial arts to defend against wild animals and bandits. He stayed at the temple for nine years, and before his departure he taught his disciples the skills he had learned, creating the martial arts legend that surrounds the Shaolin monks to this day.
