Hoa Lu is a historical site located in Ninh Binh Province, Viet Nam. The area lies approximately 90 kilometers south of Hanoi.
The site covers an area of roughly 300 hectares. In the 10th century, Hoa Lu was chosen as the first capital of an independent Vietnamese kingdom.
The presence of the seat of government in Hoa Lu marked the founding of the state of Dai Co Viet. For several decades, the area played a vital role as the kingdom's political, military, and economic center.
The Seat of Power for Two Dynasties
The history of Hoa Lu as a center of power began in 968 AD. The period was marked when Dinh Tien Hoang established the Dinh Dynasty after unifying warring factions.
As an initial step of his reign, Dinh Tien Hoang selected Hoa Lu as the capital of the Dai Co Viet kingdom. The choice of location aimed to strengthen the consolidation of power in the northern region.
The rule of the Dinh Dynasty lasted until 980 AD. Following the end of that era, the succession of royal power passed to the Early Le Dynasty.
Under the leadership of Le Dai Hanh, Hoa Lu continued its function as the seat of government. During the new era of leadership, the kingdom's focus shifted toward defending the territory from foreign expansion threats.
The main architectural legacies from both ruling eras are now preserved within two sacred building complexes. Those historical structures are the Dinh Tien Hoang Temple and the Le Dai Hanh Temple.
Both temples were erected by local residents to honor the achievements of the rulers. Within the temple area grounds, there are stone carvings, and relief artwork dating back to the 10th century.
Relocation of the Capital to Thang Long
Hoa Lu’s long-standing role as the seat of government came to an end in 1010 AD. The decision was made when Ly Thai To of the Ly Dynasty chose to relocate the kingdom’s center of power.
The new seat of government was transferred to the region of Thang Long. The location is the area known in modern times as the city of Hanoi.
The relocation was carried out considering that the Thang Long region possessed far broader flat plains. The new topography was deemed ideal for supporting economic growth and accommodating population expansion.
Following the transfer of administrative functions, Hoa Lu began to experience a shift in purpose. The ancient city was repurposed into a military defense fortress to guard the southern territory.
In addition to strengthening the defense sector, the site was maintained as a location for religious rituals. The setting was utilized by residents and royal successors to hold memorial ceremonies honoring the kingdom’s founders.
Efforts to preserve the remaining fortress walls and temples have continued across generations. Today, the historical area is officially designated as part of the UNESCO Trang An Landscape Complex.
Characteristics of Hoa Lu Natural Citadel
The primary reason behind choosing Hoa Lu as the capital was closely linked to its topography. The area stands amidst a landscape surrounded by steep limestone hills.
On the other side, the Hoang Long River flows around the outer perimeter of the region. The combination of limestone ridges and the stretch of the river formed a natural defense system.
The isolated geographical condition made it easier for royal troops to monitor enemy movements. Access into the city center was highly restricted, which requires passage through narrow cliff gaps.
The spatial layout of the Hoa Lu citadel was designed by directly utilizing the surrounding natural landscape. Its structural division was separated into an inner area and an outer area.
The outer citadel area functioned as the primary defense line as well as a residential settlement for civilians. Meanwhile, the inner citadel area was allocated specifically for the palace complex and royal family residences.
