The "Rojdestvo Bogorodichno" (Virgin Mary's Birth) Monastery of Rojhen is situated south of the village of Rojen, in Pirin Mountains. The monastery was founded in the 13th century and is among the oldest ones in Bulgaria.

The monastery is remarkable with its architectural design. The church in its current outlook has existed since the end of the 16th century. The church has three vaults, an antechamber and a small chapel in the north part. There are many well-preserved chancel– screens, dating from the 16th - 18th century. The icons on the iconostasis such as the big miraculous icon of Bogoroditsa Platitera are also interesting.

During the Turkish yoke the monastery became a religious and a cultural center. A transcript called "An interpretation of Jove" was created in the 14th century; it was decorated with 117 hand made miniatures. It has been preserved up to the present day in Jerusalem in the church of the holy Sepulcher.

The monastery is functional till date and it celebrates the birth of Virgin Mary on 8th of September.
