Istanbul Museum of the History of Science and Technology in Islam is located in the former Imperial Stables Building in Gülhane Park. The museum was opened on 25 May 2008 and displays replicas of 9th and 16th century scientific instruments of Muslim scholars. The models were all made at the Institute for the History of Arab-Islamic Sciences of the Johann Wolfgang Goethe University in Frankfurt from descriptions and drawings in contemporary texts - very few original items are present.
