The most striking feature of this site is its two long stone walls that run between spectacular cliffs of mountains. According to historical research, the walls we see today are remnants of a crucial military center that once divided the northern and southern parts of the country. Constructed by Mac Kinh Cung in the early 16th century, these fortifications were created to counter the Le-Trinh dynasty, which consistently opposed the Mac Dynasty. Although the fortress is not expansive, it stands as a testament to a tumultuous period in Vietnam's history, marked by conflict among rival factions.Photo: akisoto.com
From the peak of the fortress, perched between two majestic cliffs, visitors are treated to breathtaking views of an untouched and mysterious natural landscape. Additionally, one can observe various spike traps that once provided critical defense for the fortress. These features contributed to the Mac Dynasty's ability to maintain control and ensure border security for nearly a century.
