Persian Architecture, Iran

The great mosques of Khorasan, Isfahan, and Tabriz each used local geometry, local materials, and local building methods to express in their own ways the order, harmony, and unity of Islamic architecture. And thus when the major monuments of Islamic Persian architecture are examined, they reveal complex geometrical relationships, a studied hierarchy of form and ornament, and great depths of symbolic meaning.
In the words of Arthur U. Pope, who carried out extensive studies in ancient Persian and Islamic buildings:
"The meaningful Impact of Persian architecture is versatile. Not overwhelming but dignified, magnificent and impressive."
