This church is referred to as Metamorphosis ("Our Lord Saviour´s Transformation"). The inscription says that the church was erected in 1888 at the expense of Schilizzi Stephanovik´s sons [presumably John, Paul and Dimitrios] "in eternal memory of their parents"; photo courtesy Ioannis Kolakis 2009; translation by George Agelastos.
