There is also a large Indonesian population in the Netherlands. Many have set up their own churches in what has been termed as a "reverse mission," referring to the Dutch missionaries in the colonies. Another legacy of colonial rule in Indonesia is the legal system that was inherited from the Dutch. In 2009, the Dutch Minister of Justice Ernst Hirsch Ballin visited Indonesia in what some considered a stepping stone to reforming its legal system. Through centuries of colonial relations, numbers of cultural institutions in the Netherlands — such as Tropenmuseum and Rijksmuseum voor Volkenkunde in Leiden — has large collections of Indonesian archaeology and ethnology artifacts. Both are the leading center of Indonesian studies in Europe, specialized in its culture, history, archaeology and ethnography. The Erasmus Huis — the Netherlands' cultural centre — was established in 1970 in Jakarta. It was meant as cultural cooperation to promote art and cultural exchanges between Indonesia and the Netherlands. Besides many exhibitions, music performances and films screenings, some lectures on Dutch and Indonesian culture are being held on a regular basis in their auditorium and gallery.
