Pontevedra Principal Theatre, Neoclassical theatre in Pontevedra, Spain.

Pontevedra Principal Theatre has a neoclassical façade with symmetrical granite-framed windows and doors, and its main entrance ends in a pediment with a hollow arch. The building spans five floors and two basements, housing two exhibition rooms and an auditorium with 434 seats. Its 52-square-metre stage is equipped with a mobile platform.

The Saint Bartholomew Church stood at this location until its demolition in 1844, after which construction of the theater began two decades later. The building opened in 1878, becoming an important center for cultural life in the city.

The theatre takes its name from its function, not from a square: it belonged to the Liceo Casino, and members entered through that building's main façade. It opened on 2 August 1878 with Miguel Cepillo's company performing El esclavo de su culpa by Juan Antonio Cavestany. In April 1900 it hosted Pontevedra's first cinema projection, and in December of the same year the city's first phonograph audition.

The theater is located in Pontevedra's old town on Paio Gomez Charino Street and is easily reached on foot from the city center. Be aware that the historic interior includes stairs, so the building has some accessibility limitations for those with mobility difficulties.

The theatre's stage covers 52 square metres and has a mobile platform, while a false ceiling hides the lighting rig and improves the acoustics. The building rises five floors above two basements, which hold two exhibition rooms as well as the 434-seat auditorium.
