The church of Agios Nikolaos is located on the northern side of the island Chrissi, at the site where Tyrian purple was produced and graves are located. It dates back to the 13th century, although it has undergone more recent interventions. The temple is built on the site of an ancient building.
The temple was obviously the religious center for the hermits who lived on the island during the Byzantine period and later. It is no coincidence that there is a well with fresh water near the church and there are traces of ancient crops, probably also used by the hermits.
