Erasmus University Rotterdam is a public institution that traces its roots back to 1913. However, the university did not come to exist as it does today until 1973, when the Medical Faculty Rotterdam and the Netherlands School of Economics merged. The university is primarily located in Rotterdam, one of the largest cities in the Netherlands. It is spread across four campuses, including Campus Woudestein, the main location, and Erasmus University College, a residential liberal arts school. Tuition is higher for students from non-European Union and non-European Economic Area countries, with the exception of Swiss and Surinamese students. Student housing is available through organizations unaffiliated with the university.
