Oksanseowon is a Joseon-era seowon in Angang, Gyeongju, built in 1574 beside Jagyecheon stream to honor the virtue and scholarship of Hoejae Yi Eonjeok. Mubyeonnu, Guinidang, Mingujae, Amsujae, and Dokrakdang remain at the site. There are three entrances but only two stairways, and the west gate stays closed all year. The seowon itself does not hold many things to see.
