The Dukes of Saxony

Reputed to be the world's longest porcelain fresco, 24,000 small tiles over a distance of 102 meters and 10 metres high depict the 35 Princes of the Wettin House that ruled Saxony from 1127 to 1904.

The original fresco was done with paint during the period 1872 - 1876, but the painting was transferred to porcelain tiles in 1907 to resist weathering.

Mercifully, the tiles suffered little damage from Allied bombing of Dresden in WW2, with less than 200 needing to to be replaced.
