The chapel is located about 7 km northwest of Messolonghi and about 3 km southeast of Aitoliko. It is built on an islet, connected to the mainland by a dirt road and adjacent to the salt marshes and the pans for heating the sea water in. Lord Byron used to visit the islet on horseback during his time in Messolonghi. Today it can be visited on foot or by bicycle on the country road between Messolonghi and Aitoliko, or, if you are travelling by car, by parking your vehicle nearby and proceeding on foot. Along the road leading to it there are deposits of thermal mud used for baths.
The chapel, known as Panagia of Finikia and dedicated to the Presentation of the Virgin Mary, was originally built in 1804, according to an inscription at its southern entrance. It is considered possible that there was an earlier Byzantine phase in the nature of a monastery (Monastery of the Virgin Mary of Myrodotoussis). Today it is a simple one-room chapel with a gabled roof and a five-sided apse, which has undergone many interventions in concrete. It is surrounded by a precinct in which there is also a water-cistern.
