Seongbuk Seonjam Museum is a cultural heritage museum in Seongbuk-dong, Seoul, introducing the Joseon royal silk ceremony and the Seonjamdan altar. It displays silk drawn from silkworm cocoons and Seonjam ritual materials through 2D and 3D video and knot exhibitions. Free admission began in early May 2024, and free guided commentary is available. The exhibition space and content are small, so there is not much to see.
