When mentioning Quy Nhon, many people often immediately think of pristine beaches, untouched islands, or the stunning Eo Gió and Ky Co. However, few realize that deep beneath the clear waters, or hidden on rocky mountain slopes, there are traces of a heroic past, the most prominent and mysterious of which is perhaps the structure known as Quy Nhon Ancient Citadel. So, what is Quy Nhon Ancient Citadel, and why is it associated with such mysterious stories? Let's embark on a journey of unraveling with the Local Trips Team.
Where is Quy Nhon Ancient Citadel Located? A Position That Sparks Curiosity

The first question anyone interested in this relic asks is: where is Quy Nhon Ancient Citadel? Unlike many other ancient citadels standing proudly on land, the "Ancient Citadel" we are referring to here has a unique character. Based on known and recorded information, traces of an ancient wall structure are primarily found in the coastal and mountainous areas belonging to Nhon Hai commune and Hai Cang ward, Quy Nhon city, Binh Dinh province. More specifically, a significant and much-debated section is hidden beneath the seabed near the coast of Nhon Hai commune.
This makes pinpointing the exact location of Quy Nhon Ancient Citadel complex. It is not a single, easily identifiable point, but rather a collection of scattered vestiges, challenging our understanding and exploration. This unique location also creates a strange allure, attracting researchers, history tourists, and adventure enthusiasts.
History of Quy Nhon Ancient Citadel Formation: Mysterious Fragments

To understand the history of Quy Nhon Ancient Citadel, we need to go back a long way, to the period when the land of Binh Dinh was once the power center of the magnificent Champa culture. Binh Dinh, with its capital Vijaya (Do Ban), was one of the most important cradles of the Champa kingdom. Its coastal geographical location and strategic river mouths (like Thi Nai estuary) made it a battleground and defense point throughout many periods.
Historical documents record the existence of many citadels and defensive ramparts in Binh Dinh from the Champa period to the Dai Viet dynasties such as the Nguyen Dynasty and other feudal periods. However, what is special about the ancient wall structure in Nhon Hai is the lack of specific records in ancient texts, especially concerning a structure under the sea.
For the Local Trips Team, this mystery is precisely its most captivating aspect. It urges us to delve deeper, listen to stories from local people, and await new discoveries from archaeologists. We believe that, regardless of its exact date and purpose, these vestiges are evidence of a vibrant past and the strategic importance of the Quy Nhon - Binh Dinh region from very early times.
Who Usually Comes to Quy Nhon Ancient Citadel and For What Purpose?

Given its mysterious nature and unique location, Quy Nhon Ancient Citadel (especially the underwater wall area in Nhon Hai) attracts many different types of visitors:
- Researchers and Archaeologists: They come to survey, measure, and collect samples, hoping to decipher the mysteries of the structure's age, purpose, and construction techniques.
- History and exploration enthusiasts: You and guests with a passion for ancient history, Champa culture, or simply curiosity about the unknown, will find this place extremely fascinating. They come to witness this rare relic firsthand, take pictures of Quy Nhon Ancient Citadel, and experience the atmosphere of a special site. We have been there and clearly felt the difference when touching the mysterious mortar layer underwater.
- Tourists seeking unique experiences: Having to wait for the tide to recede to see the wall, or combining the visit with diving and snorkeling activities in Nhon Hai, offers an experience that no other place can compare to. They seek novelty and adventure.
- Local residents and students: This is part of their homeland's heritage. Locals proudly tell oral stories, while students can come here on field trips and practical studies to gain knowledge about Vietnamese History and historical tourism.
In general, those who come to this area do not simply come to check in or enjoy the scenery, but also to learn, explore, and connect with the past. I feel very happy to see the curious eyes and excitement of young people when they first hear about the underwater wall story.
