The royal family inheritance of Prince Imperial Yeong (1897-1970), the last crown prince of Korea, will come under state protection.

The Cultural Heritage Administration on Monday announced plans to protect the treasure. Some 72 artifacts excavated from mid-Chosun era military official Byeon Su's (1447-1524) tomb are also to be protected.

The royal treasure comprises 333 items of clothing and accessories such as court ceremonial robes and everyday dresses, enhancing understanding of the royal garments of the era.

The tomb contained early 16th-century clothes and wooden dolls, which are considered valuable material for the study of funeral customs of the time.
