Rangoniha mosque (Museum of manuscripts and historical documents)
The Ranguni Mosque (Rāngonihā) was built in 1921 by the workers of the Ābādān oil tanker from the Indian subcontinent, mostly Muslims from Rangoon in Myanmar, south-west of the tanker on the border between Iran and Iraq on the banks of the Arvand river.
This mosque is made of lime mortar bricks in the architectural style of Indian temples and has three doors that after the courtyard end in a building in the shape of a concrete dome on whose sides there is a staircase.
This building has four small domes and two minarets and the ceiling was built with oil pipes and railroad tracks; with the intent to hinder the infiltration of the earth's moisture in the foundations, two tunnels have also been designed.
The exterior facade of the mosque has concrete decorations with polychrome relief patterns and its mihrāb is flower-shaped and decorated with floral designs. In the interior decorations it was also made use of mirror work and some columns have floral ornaments and dome-shaped windows.
From the year 1388 (solar egira) this mosque has been used as a museum of the manuscripts and historical documents of Ābādān. Here are preserved manuscript copies of the Koran, historical documents from the qajara era to that of the first Pahlavi which include financial and commercial correspondences of Iranian traders residing in India and England with Iran; types of bills, examples of money transfers, details of exchanges and commercial letters.
