A cella (from Latin for small chamber) or naos (from the Greek for temple), is the inner chamber of a temple in classical architecture, or a shop facing the street in domestic Roman architecture (see domus).

Greek and Roman temples

Greek Temple of Apollo at Paestum with centrally located cella.

The Maison Carrée at Nimes with its cella offset behind the hexastyle portico.

In Ancient Greek and Roman temples the cella is a room at the centre of the building, usually containing a cult image or statue (execrated by Early Christians as an "idol") representing the particular deity venerated in the temple. In addition the cella may contain a table or plinth to receive votive offerings such as votive statues, precious and semi-precious stones, helmets, spear and arrow heads, and swords. The accumulated offerings made Greek and Roman temples virtual treasuries, and many of them were indeed used as treasuries during antiquity.

The cella is typically a simple, windowless, rectangular room with a door or open entrance at the front behind a colonnaded portico facade. In larger temples, the cella was typically divided by two colonnades into a central nave flanked by two aisles. A cella may also contain an adyton, an inner area restricted to access by the priests—in religions that had a consecrated priesthood—or by the temple guardians.

With very few exceptions Greek buildings were of a peripteral design that placed the cella in the center of the plan, such as the Parthenon and the Temple of Apollo at Paestum.

The Romans favoured pseudoperipteral buildings with a portico offsetting the cella to the rear. The pseudoperipteral plan uses engaged columns embedded along the side and rear walls of the cella.

The Temple of Venus and Roma built by Hadrian in Rome had two cellae arranged back-to-back enclosed by a single outer peristyle.

Etruscan temples

According to Vitruvius (Book IV.7), the Etruscan type of temples (as, for example, at Portonaccio near Veio) had three cellae, side by side, conjoined by a double row of columns on the facade. This is an entirely new setup with respect to the other types of constructions found in Etruria and the Tyrrhenian side of Italy, which have one cell with or without columns, as seen in Greece and the Orient.

Christian churches

In early Christian and Byzantine architecture, the cella is an area at the centre of the church reserved for performing the liturgy.

In later periods a small chapel or monk's cell was also called a cella.
