The Monastery of Ulann was a location on the planet Vulcan and was situated in the Kir province.

It was the home to an order of silent monks called the Ulann who lived in an area that was occupied by a hillside along the Thanor Sea coastline. In ancient times, the monks of the order operated a lighthouse which adjointed the property to aid seafarers in need. By the modern era, the lower floors of the monastery were retooled to have a printing plant and computer datanodes which were employed to disseminate information on both the teachings of Surak as well as those of the Ulann sect.
