Tianliao Stone Temple (田寮石頭廟) is a fantastical, Gaudí-esque interpretation of a Taoist temple by Southeast Asian migrant workers. Purportedly, in the 1990s, 500 men had been hired to build a highway in the area, but the contractor went out of business and they were stranded with no means. A temple took them in, after trying in vain to negotiate with the labor authorities. In return for free food and lodging, the men were asked to build a temple, which they did in the early 1990s with seashells, corals, stones and loads of imagination.
Tianliao Stone Temple worships a number of Taoist gods, but the main deity here is the Cundi Bodhisattva (準提菩薩). You'll see the main goddess and a plethora of other gold-faced Taoist deities lined up along colonnaded corridors. The temple puts out a delicious vegetarian buffet daily for devotees. Make a donation, grab a bowl and chopsticks, and join in.
To reach Tianliao Stone Temple take bus 8013 from Gangshan South MRT (崗山南站) to Tianliao (田寮) stops at Shitou Temple (石頭廟) on holidays. On other days, get off at Niuchoupu (牛稠埔) and walk. A cab from Kaohsiung takes 40 minutes (NT$800). It's best to negotiate with the driver to wait for you while you explore, as there are no taxis at the temple and few will drive out to pick you up.
The temple is also known as Cíxuán Shèngtiān Gōng (慈玄聖天宮).
