Ohio’s famed Oberlin College suspended classes on Monday after a person was spotted on campus wearing what appeared to be a white KKK robe, the latest in a string of more than a dozen racially charged incidents on campus.

In the last month the school has also found graffiti of the n-word painted on campus buildings and a swastika painted on a classroom window.

Oberlin, which counts “Girls” creator Lena Dunham, musician Liz Phair, and “Zero Dark Thirty” screenwriter Mark Boal among its alumni, is known for its open-minded past.

It was the first college in the country to establish a race-blind admissions process, and was even a stop along the Underground Railroad, which helped slaves escape to freedom.

Because of this legacy, Oberlin has been proactive about addressing the racist, homophobic, and anti-Semitic actions occurring on their campus.

In an open letter posted to the school’s website on Monday, a group of school administrators notified the community of the latest incident and announced that classes were canceled for the day in light of the events.
