Bardo Museum, Tunis

With one of the world's largest collections of mosaics, the Bardo struggles to find space to display the wondrous pieces. There is a combination of thematic presentation, and a general chronological progression as one wanders through (assuming one starts at the beginning, which Jo tends to do),

In the end, there are some examples so significant and so large, that presentation space has obviously been specifically designed and modified to hold it.
