The Dubrovnik Republic, following the purchase of Konavle in the 15th century, built the Rector's palace in the village of Saint Martin, in order to control the newfound territory and to spread its power. Shortly after, the Republic decided to build a monastery in Konavle. Firstly, the village of Saint George (Popovići) was considered to be the location, but 3 months later the location was reconsidered and the village of Saint Martin was decided to be more suitable place for monastery.

The reason: a more convenient and preferable location. The monastery was built next to the church of Saint Martin (today saint Blaise) which, in the past, had given the name to the village as well. Up until the end of the 15th century the monastery was under the Bosnian Franciscans. Franciscan friars had the authority to baptise and hold mass services. They had their own agricultural property next to the monastery but the monastery itself was leased to nobles of Dubrovnik. That lease was changed between nobles every 5 years. Since the end of the 15th century the monastery has become a part of Dubrovnik friary.

The monastery has cloister with church at south wing. Apart from its architectural importance for Konavle, the monastery holds several artwork masterpieces. For example, the wooden crucifix, work by sculptor Juraj Petrović from 15th century; main altar piece was made by famous painter Celestin Medović in 1880; in cloister are situated dozens of epigraphic inscriptions.
