The idea for the museum first emerged in the 1860s, proposed by Muhammad Khaznadar, son of the Prime Minister of Tunisia. It was formally established in the palace in 1888 and originally called the Alaoui Museum after the reigning bey, Ali III ibn al-Husayn. The name changed to the Bardo Museum only after Tunisian independence. The palace setting is no mere backdrop. Visitors walk through rooms where the Bey's apartments once stood, past gilded ceilings and carved stucco that frame the archaeological collections in an environment as remarkable as the objects themselves. The Virgil Room, named for the famous mosaic of the poet seated between the Muses, preserves the ornate ceiling of the Bey's private chambers. The Sousse Room features a golden dome. The Althiburos Room retains a musicians' tribune. Museum and palace are inseparable.

The Bardo's Roman mosaic collection is among the finest and largest in the world, assembled from excavations at Carthage, Hadrumetum, Dougga, Utica, and other sites across Tunisia. These are not abstract decoration. The mosaics depict daily life in Roman Africa with documentary precision: hunting scenes with dogs chasing wild boar, a matron at her toilet in fourth-century Carthage, bricklayers constructing a basilica, the landowner Seignor Julius surveying his estate in the fifth century. The Virgil Mosaic, from Hadrumetum, shows the poet seated between the Muses Clio and Melpomene, a third-century portrait of literary reverence. The Neptune mosaic fills an entire floor. A zodiac wheel turns in tessellated stone. Together, these works constitute an unmatched visual record of how people lived, worked, worshipped, and entertained themselves across centuries of North African history.

The Libyco-Punic collections predate the Roman material by centuries. Grimacing masks and terracotta statues from Carthaginian tombs reveal a culture that traded across the Mediterranean and buried its dead with care. Stelae from the tophet of Salammbo -- the sacred precinct associated with child sacrifice, though scholars still debate its exact nature -- bear inscriptions of major importance for Semitic epigraphy. The stele of the priest and the child, discovered in Carthage in 1921, is the department's most famous piece. Punic jewelry gleams in display cases. A statue of Baal Hammon sits enthroned. The goddess Tanit appears in multiple forms, including one with a lion's head. There is even a Carthaginian baby bottle, painted with eyes and palmettes, from the third century BC. The museum underwent a major expansion completed in 2012, adding 9,000 square meters, though the work was interrupted by the Tunisian Revolution.

On March 18, 2015, two gunmen attacked the museum, killing 22 people in the deadliest terrorist attack in Tunisian history, surpassing the 2002 Ghriba synagogue bombing. The Islamic State claimed responsibility. The attack struck at a symbol: the Bardo is not just a repository of artifacts but a statement that Tunisia's identity draws from all its layers -- Carthaginian, Roman, Byzantine, Islamic, Ottoman, French. Within a week, the museum reopened in a ceremony attended by thousands. In addition to famous works, the Islamic Department houses the Blue Quran of Kairouan, its indigo pages inscribed with gold Kufic script, alongside ceramics from North Africa and Asia Minor. Since 2014, a digital guide developed by Orange Tunisia offers audio commentary in English, French, and Arabic via smartphone -- technology serving a collection that begins in prehistory and ends, for now, in the present.
