Persian Architecture, Iran

Fundamental principles
Traditional Persian architecture has maintained a continuity that, although temporarily diverted by political internal conflicts or foreign intrusion, nonetheless has achieved a style that could hardly be mistaken for any other.
In this architecture, "there are no trivial buildings; even garden pavilions have nobility and dignity, and the humblest caravanserais generally have charm. In expressiveness and communicativity, most Persian buildings are lucid - even eloquent. The combination of intensity and simplicity of form provides immediacy, while ornament and, often, subtle proportions reward sustained observation."
