A Tapestry of Names and Enduring Beauty
Before its legendary renaming, the body of water now known as Hoan Kiem Lake bore witness to the ebb and flow of daily life in ancient Thang Long, the former name of Hanoi. Known at different times as Ta Vong (Left Observation Lake) and Huu Vong (Right Observation Lake), these names likely reflected its geographical context within the surrounding landscape. Later, its pristine clarity earned it the moniker Luc Thuy Lake, meaning “Emerald Green Water Lake,” a testament to the captivating hue that continues to enchant visitors today. Even through these evolving names, the lake remained a constant presence, a natural focal point within the developing urban landscape, offering respite and beauty to those who lived in its vicinity. The gentle sway of its waters and the verdant canopy that embraced its shores provided a timeless backdrop to the unfolding chapters of Hanoi’s story, long before the emergence of the iconic legend that would forever shape its identity.

The Mythical Origins of Hoan Kiem Lake: A King, a Sword, and a Golden Turtle
The name Hoan Kiem, meaning “Lake of the Returned Sword,” is deeply entwined with one of Vietnam’s most cherished legends, a tale that resonates through the ages and continues to fuel the collective imagination of the Vietnamese people. The story recounts the heroic deeds of King Le Loi, a pivotal figure in Vietnam’s struggle for independence against the Ming Dynasty in the 15th century. Legend has it that the Dragon King bestowed upon Le Loi a magical sword of unparalleled power, a celestial weapon that played a crucial role in his triumphant defeat of the invading forces. After years of relentless battles and ultimate victory, securing Vietnam’s hard-won freedom, King Le Loi was one day boating on the tranquil waters of Luc Thuy Lake. Suddenly, a colossal Golden Turtle emerged from the depths, its ancient eyes fixed upon the king. The turtle spoke, its voice imbued with an otherworldly wisdom, requesting the return of the divine sword to its rightful owner, the Dragon King. Without hesitation, King Le Loi respectfully relinquished the powerful weapon, which vanished into the lake as the Golden Turtle descended back into the emerald depths. In commemoration of this profound act of gratitude and the return of the sacred sword, Luc Thuy Lake was forevermore known as Hoan Kiem Lake, a name that echoes the nation’s liberation and the mystical bond between its heroes and the divine.

Turtle Tower and Ngoc Son Temple: Architectural Gems Steeped in Legend
Rising gracefully from a small island in the heart of Hoan Kiem Lake stands the iconic Turtle Tower (Thap Rua), a slender and picturesque structure that has become an enduring symbol of Hanoi. Its elegant silhouette, often shrouded in mist, evokes a sense of timelessness and serves as a constant reminder of the legend of the returned sword and the mythical Golden Turtle. While its exact origins are debated, with some attributing its construction to the late 19th century, its presence on the lake solidifies the tangible connection to the cherished folklore.

Nestled on Jade Island (Dao Ngoc) at the northern edge of the lake, the exquisite Ngoc Son Temple (Temple of the Jade Mountain) stands as another integral part of the Hoan Kiem Lake complex. This revered temple is dedicated to several significant figures in Vietnamese history and mythology, including the Confucian scholar Van Xuong, General Tran Hung Dao (a celebrated military leader), and La To (the patron saint of medicine). The temple is linked to the mainland by the strikingly beautiful, vermilion-painted Huc Bridge (The Rising Sun Bridge), its vibrant red arch reflecting gracefully on the lake’s surface. Crossing this iconic bridge is akin to stepping into a realm where history and spirituality intertwine. Within the serene confines of Ngoc Son Temple, visitors can also witness the preserved remains of one of the giant soft-shell turtles that once inhabited the lake, serving as a tangible, albeit poignant, link to the enduring legend of Hoan Kiem. These magnificent creatures, considered sacred, further deepen the mystical aura surrounding the lake.

This initiative has fostered a more relaxed and community-oriented atmosphere, allowing both locals and tourists to fully immerse themselves in the lake’s beauty and the surrounding cultural attractions without the constant flow of traffic. Families stroll along the paved pathways, couples enjoy romantic walks, and visitors capture the timeless scenery. This pedestrianization has further solidified Hoan Kiem Lake’s role as a central gathering place, a modern sanctuary where the city’s pulse slows down, allowing for a deeper appreciation of its historical and natural treasures.
