The most important site of the monastery of Saint John, apart from its catholicon, is the vestry-museum that it is considered to be the biggest museum in the Aegean. It was inaugurated in 1988 during the celebration of the 800 years since the foundation of the monastery and it is located where the cells of the monks and the oven of the 11th century used to be. The oven is preserved in the centre of the ground floor. In the showcases of the museum there are treasures of great value, the most significant of which is the parchment of the purple code (late 5th – early 6th century): Its content is the Gospel According to Mark and it is one of the sources for the text of the New Testament. The other important exhibit is the Golden Bull of Alexius I Comnenus (1088) with which he ceded the island of Patmos to Saint Christodoulos.
In the museum you can see: early printed monographs, manuscripts, silverware, vestments, the icon of Jesus in Chains (Christos Elkomenos) that is assumed to be a work of El Greco, an icon by Andreas Ritzos of the 15th century and the mosaic icon of Agios Nikolaos (Saint Nicholas) that according to tradition was brought from Constantinople to Patmos by Saint Christodoulos, as well as other icons of Cretan style. Moreover, you can see pastoral vestments, epitrachils and sacks of the 18th and 19th century, manuscripts, a Gospel of the 12th century, the book of Job of the 8th century with extraordinary representations, a copy of the icon with the vision of the Apocalypse dating back to the 17th century, the chandelier with the dragons of the Apocalypse that was transferred here from the catholicon, inscriptions, column capitals, architraves, and other fragments from the temple of Artemis that pre-existed at the site where the catholicon was built on. On the first floor the chapel of Agios Constantinos (Saint Constantine) has been preserved and there lies the armchair of the 18th century that is used in the ceremony of the Basin.
