The narthex is an architectural element typical of early Christian and Byzantine basilicas or churches consisting of the entrance or lobby area, usually located at the west end of the nave, opposite the church's main altar. Traditionally the narthex was a part of the church building, but was not considered part of the church proper. It is either an indoor area separated from the nave by a screen or rail, or an external structure such as a porch.
By extension, it can also denote a covered porch or entrance to a building.
The word comes from narthex (Medieval Latin from Classical Greek narthex νάρθηξ "giant fennel, scourge") and was the place for penitents. In Modern Greek narthekas (νάρθηκας) no longer has this meaning and is either the porch of a church, as English, or the brace of a sprained wrist or sling of a broken arm. In English the narthex is now the porch outside the church at the west end, formerly it was a part of the church itself.
The purpose of the narthex was to allow those not eligible for admittance into the general congregation (particularly catechumens and penitents) to hear and partake in the service. The narthex would often include a baptismal font so that infants or adults could be baptized there before entering the nave, and to remind other believers of their baptisms as they gathered to worship. The narthex is thus traditionally a place of penitence, and in Eastern Christianity some penitential services, such as the Little Hours during Holy Week are celebrated there, rather than in the main body of the church. In the Russian Orthodox Church funerals are traditionally held in the narthex.
Later reforms removed the requirement to exclude people from services who were not full members of the congregation, which in some traditions obviated the narthex. Church architects continued, however, to build a room before the entrance of the nave. This room could be called an inside vestibule (if it is architecturally part of the nave structure) or a porch (if it is a distinct, external structure). Some traditions still call this area the narthex as it represents the point of entry into the church, even if everyone is admitted to the nave itself.
In traditional Byzantine architecture, the narthex is divided into two distinct structures: an esonarthex (inner narthex), between the outer porch and the body of the church proper separated from the nave and aisles by a wall, arcade, colonnade, or screen; and an exonarthex (outer narthex) outside the main façade of the church, usually part of a colonnaded or arcaded atrium or quadriporticus (quadrangle). The exonarthex may be either open on the western end or enclosed, with a door leading to the outside (as in the Chora Church). The esonarthex and exonarthex have distinct liturgical functions. For instance, the procession at the Paschal Vigil will end up at the exonarthex for the reading of the Resurrection Gospel, while certain penitential services are traditionally chanted in the esonarthex.
In some Eastern Orthodox temples (churches), the narthex will be referred to as the trapeza (refectory), because in ancient times, tables would be set up there after the Divine Liturgy for the faithful to eat a common meal, similar to the agape feast of the early church. To this day, this is where the faithful will bring their baskets at Pascha (Easter) for the priest to bless the Paschal foods which they will then take back to their homes for the festive break-fast. Traditionally, the narthex is where candles and prosphora will be sold for offering during Divine Services.
The doorway leading from the narthex to the nave is sometimes referred to as the "Royal Doors", because in major cathedrals (catholica) there were several sets of doors leading into the nave, the central one being reserved only for the use of the Emperor.
By convention, ecclesiastical floor plans are shown map-fashion, with north to the top and the liturgical east to the right. Therefore, some may refer to the narthex as being at the western end of the floor plan. This is done for symbolic reasons, as scriptures say to look for Christ appearing in the east, thus the location of the altar is known as the liturgical east, regardless of the actual cardinal directions.
