Winter Room, Friday Mosque, Isfahan

The Friday Mosque of Isfahan, Iran is one of the greatest monuments in Persian Islamic architecture. Every large town has a particularly large and beautiful mosque for use on Friday by the largest congregations. One enters the great courtyard of Isfahan's Friday Mosque (Masjed-e-Jomeh) through a narrow vaulted passageway. Upon entering the courtyard, the the most notable element of the building is the immense blue mosaic-tiled iwan (a curved bay in the courtyard) with two minarets and the dome behind it that covers the main sanctuary. But I remember most the Winter Room or winter prayer hall across the courtyard behind the western iwan . What first drew me to it was undoubtably probably the contrast between the sunny, hot summer morning walking across the great courtyard and the cool dark interior. As my eyes adjusted to the light I realized it was perhaps the most beautiful room that I had ever entered. This Winter Room was divided by stout columns in to separate smaller chambers. The corners of each chamber are created by the four columns that grow wider as they rise to the ceiling in the shape of Islamic arches. Not only do the columns arch toward each other at the corners, but also to create a curving ceiling where, at the point the arches meet is a small alabaster covered window of the most remarkable luminosity. Thus on this sunny day each chamber was filled with a warm yellow light. I was transfixed by the simple beauty of this space created by stone and light.
Here is a website with a photo of the winter room chambers. I understand that the Winter Room has now been significantly modernized and has electric chandeliers. You, too, can visit the Friday Mosque of Isfahan by simply visiting this website.
