Shanmen

The Gate of Shanmen or Hall of the Shanmen or simply Shanmen (), is the entrance gate of a Buddhist temple. In ancient times, nearly all Buddhist temples had a single Shanmen gate leading into a large hall for the temple. Today, it is observed that most of the surviving Chinese Buddhist temples follow the hall style but have three main gates incorporated into their construction. After successive wars and cultural discontinuity, most Chan Buddhist temples have changed the middle gate into a hall entrance, called "Hall of Shanmen". The Shanmen is the most important gate of a Chan Buddhist temple.

==Etymology== One theory is that "Shanmen" takes its literal meaning of "Mountain Gate", because temples were traditionally built in forested mountain areas where Chan monks could seclude away from secular life. Another suggests that during various episodes of suppression of Buddhism in Chinese history, monks moved their monasteries deep into the mountains, and later built gates at the foot of the mountain to guide pilgrims to the temples. A further theory is that "Shanmen" is a corruption of "Sanmen", or "Three Gates", referring to the "three gateways" to liberations () in the Dharma – the emptiness liberation (), no-aspects liberation () and desireless liberation (). This latter view correlates with the traditional structure of Chan temples which included three gateways, said to symbolise the three gateways.
