1. The "Cultural Heart" of Sun Mega City
The emergence of Sun Mega City with a scale of up to 1,690 hectares in the South of Hanoi has created a market boom, shaping the trend of multi-functional integrated satellite urban development. However, what makes this super-city unique is the location of the complex recreating Thang Long Imperial Citadel, Sun Legacy City – a coordinate not only rich in economic potential but also carrying a noble historical and cultural mission.

1.1. Central position within the Sun Mega City mega-city
Sun Mega City is master-planned into three component mega-cities, and Sun Legacy City is the "hidden gem". The complex recreating Thang Long Imperial Citadel here is positioned as the "soul", and the "cultural heart" of the entire project. With its role as a tourism, cultural, and entertainment complex, Sun Legacy City is built to become a destination that converges the unique cultural – historical, educational, and tourism quintessence of the North.
1.2. Mission to "bridge" the past and present
Going beyond a typical tourist destination, the recreation of Thang Long Imperial Citadel at Sun Legacy City is the realization of a "grand dream" to build a bridge between the past and the present. Sun Group has chosen the location of Thang Long Imperial Citadel Sun Legacy City to create a work of significant scale and precious, sustainable cultural and historical value. Here, the nation's thousands of years of heritage will be "reborn" and vividly recreated, allowing visitors to "step into a journey back in time" to deeply feel the flow of Vietnamese cultural quintessence. The Imperial Citadel complex is expected to become a "bridge" connecting the past and the present, bringing distinct value to visitors and the community.
2. Geographical location and traffic connection advantages
The location of Thang Long Imperial Citadel Sun Legacy City was chosen with strategic consideration to create an international cultural destination, meeting both modern traffic connection requirements and profound historical significance.
2.1. Strategic coordinates of the Southern Capital's gateway
The tourism and cultural complex recreating Thang Long Imperial Citadel is located within the Sun Mega City mega-city, situated in the south of Hanoi. Administratively, this complex is located in the former Ha Nam province, now Ninh Binh province.

This location is assessed as a strategic coordinate with a "golden distance" to the Capital's center: only about 50km from Hanoi center, equivalent to about 45 minutes of travel. With rapid urbanization, owning a large-scale tourism complex, rich in cultural values, located right at the southern gateway of the Capital brings immense competitive advantage, ensuring optimal accessibility for both domestic and international tourists.
2.2. Comprehensive connectivity infrastructure
To realize the vision of a multi-functional super-city and a world-class tourist destination, Sun Mega City has fully utilized the region's modern transportation infrastructure network.
Highway connectivity: This location directly benefits from the Phap Van – Cau Gie – Ninh Binh expressway and key national routes, shortening travel time for residents and tourists.
Regional linkage: From this coordinate, the complex easily connects quickly to neighboring key economic regions such as the former Ninh Binh province, former Nam Dinh, former Thai Binh (now part of the new Ninh Binh province). Synchronized transportation infrastructure strongly promotes the economy, trade, and services of the entire region, making Sun Legacy City an ideal inter-regional trade and tourism hub.
"Auspicious energy convergence" terrain: The complex is located at the center of the basin of three important ancient rivers: Day River, Nhue River, and Chau Giang River. This terrain not only has feng shui value but also creates sustainable development potential for the project.
3. Historical significance and feng shui terrain
The choice of Hoang Thanh Thang Long Sun Legacy City location is not only based on transportation connectivity potential but also on honoring unique cultural imprints and feng shui terrain. Sun Group has created this complex at a historically significant coordinate, where the thousand-year-old spirit of the nation's rivers and mountains converges.
3.1. Sacred land of Chau River, Doi Mountain
This cultural tourism complex is located in the former Ha Nam province, majestically situated at the foot of Long Doi Son Mountain and adjacent to the legendary Chau River. This area is known as the land of "Doi Mountain, Chau River" rich in historical sediment.

In terms of feng shui, the project is strategically located at the confluence of three important ancient rivers: the Day River, the Nhue River, and the Chau Giang River. This "gathering of vital energy" terrain not only holds deep spiritual value but also creates sustainable development potential for the Sun Mega City super-urban area. Long Doi Son Mountain was once a Buddhist center in the old Son Nam region, contributing to the sacredness of this area.
3.2. Linked to the historical journey of capital relocation
The choice of location in the former Ha Nam province is a symbolic decision, as this area is the historical gateway linked to a major turning point for the nation.
Footprints of King Ly Cong Uan: This location once bore the "footprints" of King Ly Cong Uan on his historical journey to relocate the capital from Hoa Lu (Ninh Binh) to Dai La (Thang Long) in 1010. The book Dai Viet Su Ky Toan Thu records that King Ly Cong Uan, along with his civil and military officials, traveled by waterway, believed to have gone upstream along the Day River to Phu Ly, then turned into the Chau Giang River before heading to Thang Long.
Historical Witness: Right on the peak of Long Doi Son Mountain, the nearly 1,000-year-old Long Doi Pagoda still preserves the Sung Thien Dien Linh stele. This ancient stele, with the calligraphy of King Ly Nhan Tong, is the only surviving original text from the Ly Dynasty that mentions the Thang Long Capital, along with important symbols such as Cam Thanh, Doan Mon, and Dien Huu Pagoda (One Pillar Pagoda).
It is the legends and precious heritage from this gateway land that have become the inspiration for creating the cultural tourism complex at Sun Legacy City, reviving the most glorious period in Vietnam's cultural flow: the Ly-Tran dynasties (11th–14th centuries).
4. Vision and role in regional development
The Thang Long Imperial Citadel Sun Legacy City location is not just a prime geographical coordinate but also the foundation for Sun Group to realize its vision of a cultural tourism complex with a grand mission: to promote regional growth and affirm Vietnam's cultural position on the international stage.
4.1. International cultural tourism hub and large-scale film studio
The strategic location of the complex at the southern gateway of the Capital, along with the idea of meticulously recreating the Thang Long Imperial Citadel of the Ly-Tran period, helps this place become a new "cultural icon" of Vietnam.

International Stature: This complex is expected to become an international-level historical and cultural destination. The project is likened to the famous "Hengdian World Studios" model in China, where the voice of heritage helps visitors "live with culture, experience culture".
Historical Film Studio: The complex recreating Thang Long Imperial Citadel at Sun Legacy City also aims to develop into a large-scale ancient costume film studio, ideal for producing historical cinematic works rich in Vietnamese identity. This is a model that has proven effective in China, Japan, and South Korea.
4.2. Regional growth drivers and investment potential
Sun Mega City, a super-metropolis with a scale of 1,690 hectares, is projected to ignite strong growth momentum for the southern area of Hanoi. The presence of this unique cultural tourism complex will attract a wave of investment and create tens of thousands of direct and indirect jobs in tourism, services, construction, education, and healthcare.
The location of Thang Long Imperial Citadel Sun Legacy City is adjacent to major amenities and integrated social infrastructure, creating attractive investment potential such as:
The project is located near Nam Cao University City - an area expected to gather hundreds of thousands of students and experts.
Adjacent to two central hospitals, Viet Duc and Bach Mai (second campus), contributing to enhancing the quality of life and services in the area.
Thanks to its systematic planning, integrated infrastructure, and the combination of tourism – culture – education ecosystems, the project is not only suitable for business investment but also possesses long-term price appreciation potential. This reflects Sun Group's strategic vision in developing tourism linked with cultural preservation, creating long-term value for the community and the destination.
The location of Thang Long Imperial Citadel Sun Legacy City is a perfect combination of historical elements, "auspicious energy gathering" feng shui, and modern transportation connectivity advantages. This place is not only the "cultural heart" of the Sun Mega City super-metropolis but also a true "connector", bringing the nation's thousand-year history closer to the public and turning the land of Doi Mountain and Chau River into a new focal point on Vietnam's tourism map.
