The Nam O historical relic cluster includes the Nam O village communal house, Whale Temple, a worship place dedicated to the souls of the fallen Vietnamese revolutionary soldiers in their struggle against the French forces in the years of 1858, 1859, and 1862, plus a temple dedicated to Goddess Liễu Hạnh, one of four immortals in Vietnamese legends and the Lang hundreds-year-old mysterious square well.

The cluster boasts many cultural and historical marks and values, demonstrating the continuation between the Cham and Vietnamese cultures with geological stratigraphy (layers of various sediments representing different periods of time).

Da Nang People's Committee issued a decision to recognize the cluster as a municipal-level historical relic site on 27 November 2020.

Till date, the municipal Department of Culture and Sports has basically completed the procedures for the restoration and embellishment of the Nam O historical relic cluster at an estimated cost of more than 25 billion VND. Work is slated to start on this project in the rest of this year.

After the reception of the certificate, the Fish Worshipping festival took place with many solemn rituals and exciting traditional festive activities.

The festival aimed at honoring the Gods of the Sea and the Whale, as well as praying for a successful fishing season ahead. In addition, it offered a chance for local fishermen to pay tribute to their predecessors who had made great efforts to the development of the local fisheries sector.

One of the highlights of the solemn rituals was a ceremony to make offerings to the Whale God.
