Monce-Naguro - St. George's Island

The islands of Monce-Naguro and St. George's Island are only accessible by boat in the summer. The language used to be Serbian, but now is spoken as part of an independent country called Montenegro. There are two island monasteries: Ostero Vaux (O-S-T-R-V-O) and St. Mary's (I want to say it's St.Mary's).
