The museum of measurement
The museum of the weight and size of the city of Tabriz was established starting from the year 1380 (solar Hegira) in the spaces of the Casa Salmāsi which dates back to the qajara era and was built in 1381 (lunar Hegira) on three sides of the courtyard (width 650 square meters) on two floors with 875 square meters foundation.
The building consists of an entrance with brickwork, a vestibule and an entrance corridor to the large room with a fountain in the center, a large living room with three doors to the north and living rooms (for residential use) adjacent to the east and west, a water warehouse and a small garden.
The main part of the building is located on the northern side of the courtyard. Even the facades located to the west and east have services and rooms for residential purposes. In the adjacent entrances of the western hall, two colonnaded iwān have been added.
The lower floor of the northern hall is used as a large room with a fountain in the center and as a summer residence.
The building has ornaments in the center of the room, around the arches, ceilings and fireplaces. The ceiling of the northern hall and the northern façade from the interior of the courtyard has stucco ornaments together with mirror decorations. The up and down windows with colored glass and the workmanship of the stucco and brick portal have the appearance of candelabra. The arch of the vestibule is covered with raised bricks and the ceiling of the room with the fountain at the center has a four-sided arch. The columns of the iwān have worked stucco capitals. The museum exhibits various weight instruments such as goldsmith scales, large scales used in market squares, weighing stones, containers for oil, instruments relating to astronomy such as the astrolabe, measuring instruments relating to meteorology, compasses and clocks from past centuries. In this museum is also preserved a trunk of a tree of five million years dating back to the Pliocene and to the periods of the Cenozoic era. The material of this tree with the passage of time has turned into silica stone fossilizing. Even the vessels and sections of this tree, with the absorption of organic substances, have hardened and the outer layer has taken on a color similar to that of rusty iron. An example of the first petrol pumps in Iran that is a hand pump is also preserved in the museum of weight and size. This is about a hundred years old and is a production of England. In this museum there is also a historical clock with the image of Caesar Augustus, Roman emperor manufactured in the 17 century AD in the city of Cannes in France.
