Hwajinpo (화진포) is named so because there are sweet briers that bloom by the lake, and it is one of nature’s great lagoons. It is designated Gangwon Provincial Monument No. 10 with a circumference of about 16 km, and it has a wide reed field which is an important place for migratory birds and swans in the winter. Hwajinpo Lake is surrounded by evergreens and white sandy beaches; it is a lagoon where the river and the sea meet. Materials drifting down the river deposited at the bottom of the river become a sandy beach that eventually block off the river from the sea, creating a lagoon. Hwajinpo Lake is the largest lagoon near the East Sea, and has many ancient artifacts around it, such as the Ten Goindol rocks (also called Jiseokmyeo) scattered around the lake. Because of its excellent scenery, Kim Il-Seong (1912-1994) of North Korea and the South Korean president Lee Seung-Man (1875-1965) had summer houses here after the independence of Korea in 1945. The two houses that originally faced each other with the lake at the center are gone now, but the sites still remain as tourist destinations. They have been converted to Hwajinpo’s Museum of History, and opened to public as a security exhibit center.
