Gwangseongbo Fortress’s outer wall from the Goryeo era was mended in 1618. The fortress was built in 1656 and the outpost was constructed in 1679. It was completely remodeled into a masonry castle with gates in 1745. During Sinmiyangyo (the American invasion in 1871), Gwangseongbo was the fiercest battle ground in Ganghwa. On April 24, 1871, a fleet with 1,230 American naval forces led by Rear Admiral John Rodgers landed on Ganghwado Island to demand the opening of Korea's ports and commerce. The armed forces attacked Chojijin Fortress and Deokjinjin Camp, then marched to Gwangseongbo Fortress, where they engaged in close combat with the warriors of Joseon. Although General Eo Jae-yeon and the other warriors were poorly equipped with far inferior weapons, they bravely fought to the death against the invading forces.The battlefield ruins of the fortress and the gate towers such as Anhaeru, Gwangseongdon, Sondolmokdon, and Yongdudon were repaired in 1977. The twin tombs of General Eo Jae-Yeon and his brother Eo Jae-seon, along with the anonymous tombs of warriors who died on the battlefield were also honorably arranged at the same time. Furthermore, a stone monument commemorating the restoration of Ganghwa Battlefield was erected on Yongdudondae Post.In 1988, an extensive rest area was created toward the shore for visitors’ convenience. Gwangseongbo Fortress is presently designated as Historical Relic No. 227. A religious service known as Gwangseongje is held annually to commemorate the patriotic spirits of General Eo Jae-yeon and other unnamed warriors. This service takes place at 11 a.m. on every April 24th of the lunar calendar.

The Sorae Ecology Park was once a facility used to produce salt until 1996.

The Sorae Ecology Park also provides a history to the facility and houses a Nature Learning Center, where visitors can experience sea salt production and learn more about the various wildlife and plants living in the marsh.

Yeonan Pier is the starting point for all coastal passenger ships bound for the numerous islands in the western sea. The nearby Incheon Fish Market is always bustling with people who come to buy fresh fish and pickled fish at reasonable prices.

The ships here are also available for rent for various purposes so events like reunions and seminars can be held aboard the ship.

Goryeogung Palace Site on Ganghwado Island is the site of the royal palace where the people of the Goryeo Dynasty (918-1392) resisted the Mongolian invasion for 39 years. In June 1232, King Gojong moved his capital to Ganghwa on account of its natural and strategic advantages. The construction of the government office and the royal palace in Ganghwa was completed in 1234. Ganghwado Island holds historical significance as the place where metal type was developed and where the Palman Daejanggyeong (the Tripitaka Koreana printing woodblocks) were made during the Goryeo dynasty. Upon the conclusion of the peace treaty with Mongolian forces in May 1270, the capital was moved back to Gaeseong (present-day Gaeseong in North Korea), and the royal palace in Ganghwa was subsequently destroyed.In the Joseon Dynasty (1392-1897), Haenggung (the king’s temporary palace) was constructed on the same site as the Goreyo palace. During the Byeongjahoran (Chinese invasion of Korea) in 1637, the palace was conquered by the force of Ching dynasty of China. Afterward, Ganghwa Yusubu (Ganghwa governor’s office) buildings were built on the palace site. Nowadays, the only structures that remain are the Dongheon main office (built in 1638) and Ibangcheong administration office (built in 1654). The palace and its subsidiary buildings were restored in 1977.

Goryeosan Mountain, once referred to as Oryeonsan, is a mountain rich in folklore. Legend has it that in the year 416 (during the reign of King Jangsu of Goguryeo), a Buddhist monk named Cheonchukguk climbed Goryeosan Mountain and found Oryeonji Pond where the five-colored lotus flowers bloomed. The monk picked the lotus flower petals and blew them into the air. He then built a temple where each of the petals had landed, naming the temples according to their corresponding color: Jeokseoksa, formerly Jeokryeonsa Temple (red lotus), Baengnyeonsa Temple (white lotus), Cheongryeonsa Temple (blue lotus), Hwangryeonsa Temple (yellow lotus), and Heungnyeonsa Temple (black lotus).Around 130 dolmens are distributed along the foot of Goryeosan Mountain. Sirumisan Mountain, on the northern side of Goryeosan Mountain is said to have been the birthplace of General Yeongaesomun of the Goguryeo Kingdom.

Recently, the government announced its plan to designate part of Guleopdo Island as a natural monument. This island, located to the southwest of Deokjeokdo Island in Incheon, is indeed a beautiful island, boasting unique coastal landscape formed by strong tides, waves, and wind. Though there are numerous islands near Deokjeokdo, Guleopdo Island boasts such splendid beauty that it is said to be unmatched by any of the other islands in the West Sea. The island has been the dream of resort developers for years. The north beach of Guleopdo, Seondanyeo (near Baekado) and Jaraseom boast oddly-formed rocks and an exquisite coastal landscape. It’s a prime spot for fishing enthusiasts and is known for its abundance of flatfish, rock trout, and soft clams. Just fifteen minutes to the west of the dock facility in Guleopdo is Mokgimi Beach (a costal sand dune) that has a unique elephant-shape because of the rocks that were carried there by strong waves. Other rocks have fallen down from the nearby cliffs. Along the coast, there is also a beautiful white sandy beach that stretches over 600m. Not well-known to tourists as of yet, this beach is a great spot to enjoy calm, relaxed summer vacations.

Seopori Beach, designated as a national tourism area, is surrounded by a luxurious forest of 100-year-old pine trees. The moderately sloped, white sand beach extends 3 kilometers in length and 300 meters in x_width. The beach and the pine tree forest provide a great recreational area for the 100,000 annual visitors. Leisure facilities include a vast sports field, seaside playground, tennis court, restaurants, karaoke, bicycle rentals, and more. Visitors can enjoy fishing from the rocks on the seashore, swimming in the clean sea, and strolling through the pine forest to appreciate the scenic surroundings.

The Gwanghwado and Incheon areas are known for their plentiful catches of baendaengi (large-eyed herring). After a little street started specializing in serving baendaengi some 30 years ago, the fish has continued to grow in popularity.Located in Guwol-dong, across from the Incheon Culture & Arts Center, Baendaengi Street has expanded, and so has the variety of dishes served. Visitors can try baendaengi prepared sashimi-style, roasted, or in a spicy soup. For this particular species of herring, locals believe the flavor is best in March and April when they grow to their largest size. Salted Baendaengi also makes an excellent side-dish for Korean meals.*Baendaengi is one of many types of small prey fish referred to as ‘Soeo’ for their fierce struggle in fishing nets. Soeo have internal organs that are proportionally smaller than other species of fish and are known for their feisty nature. These attributes are thought to signify a stress-filled life, which is why many Koreans refer to narrow-minded or hot-tempered people as ‘baendeangi.’
