At the abandoned settlement of Frathias, near the monastery of Xera Xyla, there is the church of Saint John, which for once was the temple of a small monastery. The church is single-nave, arched and at the entrance there is the date 1590 indicated.
Around the monastery there are several ruined buildings and cells. East of the church, next to the cells there are remains of an entrance, built in 1906 by the monks of the monastery of Xera Xyla.
The site of the monastery seems to be delimited by the cells, the entrance and the ruined surrounding walls. In the surrounding area west of the temple there are burials and two ovens. The monastery was mentioned in 1832 as dependence of the monastery of Xera Xyla.
