What are the sections of the congregation section of church nave?

The congregation section of the main nave is divided by pillars into two sections. To the south (i.e., to the right of the altar when you face the east) is an area or section that used to be reserved for nuns, then for widows, then for women with children, and lastly for young ladies. However nowadays, this separation does not exist anymore. To the north (i.e., to the left of the altar when you face the east) is an area or section reserved for men. This way children enjoy the Liturgy with the entire congregation. Women are on the right side of men, as the Queen sits at the right hand of the King (Ps. 45:9).
