 Like so many monuments of central Iran, the Jameh Mosque of Saveh’s core is of the 12th century, and its single surviving minaret is dated in 1110 and 1061.The proportions of its façade are also related to systems of proportion established in the 12th century, although the work itself is, apparently, of the early 16th.Recent discoveries indicate that the mosque might have been constructed on the foundations of an older mosque dating back to the 10th.
