The Piliers de Tutelle (meaning Pillars of Guardianship in French) was an important Gallo-Roman monument erected in the third century on the approximate location of the southwest corner of the Grand Théâtre of Bordeaux, a city in southwestern France.

The pillars with the reliefs were bilateral, meaning that the interior of the Piliers de Tutelle sported the same caryatids, vases and arches.

[1] The study of the lapidary collection kept at the Aquitaine Museum in Bordeaux made it possible to highlight a set of blocks that could belong to an elevation of the monument as described by Claude Perrault.

[3] The Piliers de Tutelle were built around the late second or early third century under the Severan dynasty which brought the region a period of prosperity from which Bordeaux greatly benefited.

[4] In the middle of the 9th century, the Arab geographer Al-Himyarī described this monument for the first time, writing that "north of Bordeaux is a building that can be seen from afar and which rests on tall, thick columns: this was the palace of Titus".

The Piliers de Tutelle was also compared to the so-called "Portico of the Giants" from the Odeon of Agrippa in the Ancient Agora of Athens.
