The Museum's Byzantine and Post-Byzantine icons constitute one of its largest and most important collections. The collection stands out not just by the exceptionally large number of works it contains - ca 3,000 - but also by the wide range of iconographies it covers across the chronological spectrum of Byzantine and Post-Byzantine art, which moreover come from all over Greece, Asia Minor, the Balkans and Russia.
There are also 250 diptychs and triptychs in the collection, dating from the 15th to the 19th century. These artefacts were for the most part works of private devotion.
Some woodcarvings, such as three carved wooden sanctuary iconostases from churches in the Ionian Islands and Northern Greece, episcopal thrones, etc. complete the collection.
