According to historical documents, the original temple was just a simple and small shrine, built in the late 18^th century to worship a young girl named Lê Thị Hồng.

According to legend, she was born in Tam Quan district of Binh Dinh province and drown in the sea on her way to Long Hai beach by boat. The body of the 16-year-old girl washed up on Long Hai Beach was buried in Co Son hill by local people. Since the local people believe that she was a sacred goddess who helped and protected the locals in divine ways.

In 1930, Long Hai fishermen moved the temple up Ky Van hill. In 1987, Dinh Co temple was rebuilt after a fire. In 2006-2007, it was reconstructed again. Today, the construction of Dinh Co temple has a total area of over 1,000 m2 with ancient architectural designs mixed with modern styles.

The sanctum of the temple has seven altars. The centre of the altar is a 0.5 m statue of the goddess dressed in red with a gold lame trim. 

In the temple, there is a separate room for gifts offered  by people (mainly clothes and crown)

Behind the temple, there is a way to Ky Van hill

From the top of the hill, you can see Long Hai beach in the distance.

Every year, there is a three-day festival called Nghinh Co Festival on 10-12 of second lunar month that attracts flocks of pilgrims from around the country.

In 1995, Dinh Co temple was recognized as the national historical and cultural relic.
