Time Out says
Istanbul's foremost modern arts museum, Istanbul Modern moved to a temporary space in Beyoğlu in May 2018, where it will welcome visitors until its new building is completed in 2021. Founded in 2004 as Turkey’s first museum of modern and contemporary art, Istanbul Modern offers a variety of cultural activities in its permanent and temporary exhibition halls, photography gallery, spaces for educational and social programs, library, cinema, café, and store. The in-house cinema regularly screens independent films programmed around ongoing exhibitions, contemporary directors and stand-alone events.
