There are tens of thousands of museums around the world that are interested in collecting objects of scientific, artistic or historical value and making them available to the public through exhibits that may be permanent or temporary. The Arabic Encyclopedia defines it as a "house for the preservation of ancient monuments, rare antiques, masterpieces of sculptures and paintings, and all related to cultural heritage." The museum may include works of art, history and technology.

The word "museum" in Arabic means the place where rare and precious objects are collected and valued as time passes. The origin of the English Museum is the Greek origin of the word "mountain lady".

The first museum for the public was opened in 1683 at the University of Oxford in London. It presented a collection of strange and rare things given by the English scholar Elias Ashmul to the university. In the late 20th century, many museums introduced new systems using modern technology, Computer equipment, sound, light and video presentations, which have made museums more dynamic and attractive, and helped improve the cultural mission of the museums.
