In a central area of the Sia village, a church in the name of Panagia Chryseleousa is built. The church has been built in 1756 and in 1886 it has been extended to be in the state it is found today. It can receive up to 200 believers.
The church of the outside is built of stone and it is probable that the huge steeple was built in a later on since it presents a difference in the stone.
It is a monument that each visitor has things to gain from if they visit it.
