- Hall of the Abencerrajes
The ceiling in the Hall of Abencerrajes. The decorations are called muqarnas, and in the museum is a very instructive exhibition on how such a ceiling was made. Basically a lot A LOT of tiny pieces (alveoles) put together. - Basilique Notre-Dame de Beaune
A magnificent stained glass window. But I have no idea how old it is. May be old, but my uneducated guess would say quite recent.
