Located at the mouth of the Beigang River, the temple is dedicated to the sea goddess Mazu.

Gangkou Temple was founded in 1684 (Kangxi 33) by a settler named Lin Kai (林楷).

Lin Kai migrated from Meizhou Island, the birthplace of Mazu, and landed near the temple's current site.

[3] Gangkou Temple hosts a major Ghost Festival event in the seventh month of the lunar calendar.

Therefore, every year, these residents hold a celebration at Gangkou Temple to pray for protection against further floods.
