Jeong Yak-yong wrote over 500 volumes of books covering philosophy, science, and practical government reform during his lifetime.
The site features a functional replica of the Geojunggi, a crane system Jeong Yak-yong designed to facilitate the construction of Hwaseong Fortress.
The name 'Yeoyudang' reflects Jeong's personal motto, drawn from a classic text, signifying a cautious and reflective approach to life.
Jeong Yak-yong is considered the foundational figure of Silhak (Practical Learning), a school of thought advocating for science and technology over abstract Confucianism.
The tomb is positioned on the hills behind the house, following traditional Korean geomantic principles for ancestral burial sites.
The Dasan Jeong Yak-yong Heritage Site commemorates the life and scholarly achievements of the late Joseon Dynasty philosopher, reformer, and polymath Jeong Yak-yong. The site is situated at his birthplace and final resting place in Namyangju, where he spent his later years in exile. Key features include the Yeoyudang house, where he was born and eventually returned after 18 years of exile in Gangjin. The grounds contain his tomb, a memorial hall housing historical artifacts, and a bronze statue of the philosopher. Visitors can explore displays related to his contributions to science, literature, and legal reform, including his inventions like the Geojunggi crane. The site reflects the traditional architectural style of the Joseon period and is integrated into the larger Dasan Ecological Park along the Bukhan River. The memorial hall showcases manuscripts, personal belongings, and replicas of his agricultural and architectural designs.
