The museum of measurement
The museum of weight and measurement of the city of Tabriz was established starting from the year 1380 (solar Egira) in the spaces of the Casa Salmasi which dates back to the Qajar era and was built in 1381 (lunar Egira) on three sides of the courtyard (650 square meters wide) on two floors with foundations of 875 square meters.
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 north facade from inside the courtyard have stucco ornaments together with mirror decorations. The up and down windows with colored glass and the workmanship of the stucco and brick portal presents the appearance of candelabra. The arch of the vestibule is covered with relief bricks and the ceiling of the room with the fountain in the center has a four-sided arch. The iwān columns have worked stucco capitals. The museum displays various weight instruments such as goldsmith's scales, large scales used in market squares, stone weighers, oil containers, astronomy-related tools such as the astrolabe, meteorological measuring instruments, compasses and watches of past centuries. In this museum there is also a trunk of a five million year old tree dating back to the Pliocene and the periods of the Cenozoic era. Over time, the material of this tree has turned into siliceous stone and fossilized. Even the pots 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. In the museum of weight and measurement there is also an example of the first existing petrol pumps in Iran which is a hand pump. 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 17th century AD in the city of Cannes in France.
