Porta Carmentalis

The Carmental Gate, also known by its Latin name as the Porta Carmentalis, was a double gate in the Servian Walls of ancient Rome. It was named for a nearby shrine to the goddess or nymph Carmenta, whose importance in early Roman religion is also indicated by the assignment of one of the fifteen flamines to her cult, and by the archaic festival in her honor, the Carmentalia. The shrine was to the right as one exited the gate.

The gate's two arches seem to have been set at angles, and were known by separate names. It was unlucky to leave the city through the arch called Porta Scelerata ("Accursed Gate"), which was supposed to have been named for the military disaster at Cremera in 479 or 478 BC, since the 306 Fabii who died had departed through it. The Servian Walls, however, did not exist at that time. The accursed nature of the gate probably derives from the transport of corpses out of the city proper to funeral pyres on the Campus Martius. The family tomb of the Claudii was located outside the Carmental Gate.

The other gate was the Porta Triumphalis. A governor returning from his province could not enter through this gate unless he had been awarded a triumph.
