Gwangnaru, that is, Gwangjin was also referred to as Yangjin since it was called the ferry where there are many willows. Gwangnaru was the final destination where logs were cut off at the Gangwondo area and then flown down the Han River by making rafts. Moreover, this is the fastest ferry for going from Seoul to Gwangju, Gyeonggi-Do.

Before the construction of the Jamsil Bridge , Olympic Bridge and Gwangjin Bridge , this was a place with a wide river width where one could not help, but cross, relying on a ferryboat. Moreover, this was a place where poets and painters would visit to create a lively mood due to the beautiful scenery that unfolds at the edge of the Mt. Achasan and the landscape on the river .

Meanwhile, Gwangnaru is a place where the pain of separation is accumulated since Prince Yangryeong, the older brother of King Sejong, was going down to Gwangju after his father, King Taejong, let go off him after Prince Yangryeong discarded his position as the heir. The father-son relationship of King Taejong and his eldest son, Prince Yangryeong, flew down by melting in the blue waters of the Han River .

Prince Yangryeong was selected as the heir at the age of nine during the 4 th year of King Taejong's reign (1404). However, he could not adapt well to the etiquettes required of prince-heir, strict Confucian education and strict like in the palace due to his free-spiritedness. Thus, he used to sneak out of the place to hunt or to enjoy taste of life.
To this, King Taejong admonished him several times, but Prince Yangryeong soon fell for the pleasures once again after a while after trying to hold him, and his qualities as prince heir were questioned after he became the target of strict Confucian scholars.

However, the character, reading habits, academic and military knowledge of his younger brother, Prince Chungryeong, surpassed those of his, and thus Prince Chungryeong's abilities were highly recognized by many servants and King Taejong. Amidst this situation, Prince Yangryeong often engaged in actions that went against the wish of King Taejong, and the people who used to teach him where often subjected to King Taejong's admonishments.

Likewise, when the relationship between King Taejong and his heir became increasingly estranged, Prince Yangryeong is abdicated during the 18 th year of King Taejong's reign (1418) in June amidst the opposition of Hwang Hee and Lee Jik.
And Yu Jung Hyun and others supported King Taejong's decision to designate Chungryeong as the new heir.

It is said that King Taejong cried for a long time after this decision was finalized. Although everything took place effectively, following each and every procedure that was prepared, rules was followed extremely fairly and serenely on the outside in order to avoid the criticism and ripple among people.

Soon after, the initiative of sending the former heir, Prince Yangryeong, to the outside world was pursed. servants such as Yu Jung Hyun and others recommended exiling him to Chuncheon. Although he approved at first, King Taejong soon ordered that he be sent to nearby Gwangju. Since it was not possible to cross the river since the water level had increased due to the rain that continued on for days, he was allowed to stay in his private residence until the river would decrease.
However, Yu Jung Hyun and others insisted that,
"It is not possible for him to stay in Seoul ."
Without options, King Taejong forced him to leave for Gwangju immediately. To the Prince Yangryeong who is leaving, the King assigned 10 of the female servants and a couple of retainers. And he let him take along a woman that he loved, and he allowed the former heir to leave with various materials that he was using daily.
However, he was to leave behind only the whip and arrow. King Taejong ordered that everything necessary to ensure comfortable life for Prince Yangryeong be provided for. On the day of his departure, Prince Yangryeong asked Won Yun who was following him up to the Dongdaemun, ¡°Why are you following me?
To this, Won Yun, replied, ¡°I was ordered to escort you."
Prince Yangryeong then said with teary eyes, while getting on a boat in Gwangnaru,
"I will not be able to see this land ever again!"
When he was fare welling off Won Yun, he said to him,
" ...... It is only the grace of the King that I did not die even when I sinned. I do not know how to repay this grace.... Now that I wronged him as a son, how can I face him later on?"
Won Yun, who was escorting him, returned with two women, saying that the number of women in the Prince Yangryeong's group was greater than the number allowed by the country.

After hearing this, King Taejong said, "They are both his concubines. It is your fault that you brought them back", and immediately ordered them back to Gwangnaru.

To Prince Yangryeong who was exiled to Gwangju, he was allowed to leave only with Analects of Confucius and and The Great Learning when it came to books.

Around June, King Taejong sent down Choi Han, an official in the Royal Household to Gwangju to see how Prince Yangryeong is living and acting. After returning from Gwangju, Choi Han reported that Prince Yangryeong is leading a very lonesome and mundane life.

When King Taejong was first sending off Prince Yangryeong, he told him,
"You have not wronged Chungryeong. Live your life comfortably", and advised him and Prince Chungryeong (Sejong) not to discard the loyalty of brothers. Sejong, his younger brother, uphold him, and blocked officials' criticism and expostulation

Likewise, Gwangnaru where Prince Yangryeong shed tears has no traces. Merely a stone post shows that this was the Gwangnaru, but this stone post is not conspicuous unless one looks closely.
saengdoryang is made towards the lower part of the Sheraton Walker Hill Hotel's entrance. This is the Gwangnaru or the willow ferry , and Amsa-Dong and Jamsil are visible across the river.
