Haeundae takes its name from the ninth century Silla scholar and poet Ch'oe Ch'i-wŏn (literary name Haeun, or "Sea and Clouds"), who, according to a historical account, admired the view from the beach and built a pavilion nearby.

[3] On Haeundae Dongbaek Island, there is a statue of Ch'oe Ch'i-wŏn, a Confucian scholar of the Unified Silla Period, and a monument.

During the reign of Queen Jinseong during the Unified Silla Period, Ch'oe Ch'i-wŏn lamented that there was no place to write his studies.

This area lies in the southern shadow of the mountain Jangsan to the north, and is bounded in the south by Haeundae Station on the Dalmaji Gogae line of the Korean National Railroad.

Additional apartment blocks are under construction, with water resorts and related facilities, for use by the public, also planned for Marine City.

[10] Ch'oe Ch'i-wŏn (857-10th century), an official and poet from the late Unified Silla Dynasty (668-935), was so struck by its beauty that he decided to extend his stay there.

Known as the largest beach in South Korea in terms of size and area, its unique location near the city center and affluent residential skyline makes it one of the most desirable places to live.

Previously an old residential neighbourhood, Haeridan-gil (해리단길) has transformed in the last decade into a trendy area where many young locals spend their weekends.

[15] Haeundae has been featured in numerous K-Dramas, with the beach and Dongbaekseom being used as a filming location for Seoul Broadcasting System's 2008 drama Star's Lover.
