The second-oldest building on campus, it was constructed in 1797, several years after West College. They were creative with the building names back when the college was founded, weren't they?
Anyway, East College is now one of the two first-year dorms in the Odd Quad, along with Fayerweather Hall. Both of theses dorms feature horizontal entires, unlike the vertical entries in Morgan, Lehman, Sage, and Williams Hall. East is located directly across the quad from Currier, and is thus an excellent position for aspiring WARPies or Deviants. Unfortunately or fortunately, depending on the day of the week, it is also located directly across the eyeballs from Goodrich, which can get rather annoying for first-years trying to do work on weekends, but does make stopping for a cuppa on the way to class quite convenient.
It also features relatively large rooms, single-sex restrooms, and the only frosh entry easily represented by a local road sign (which college security officials often lecture against stealing at the beginning of the year).
Oh, and since I replaced a flagrantly partisan anti-East entry, I might as well add that East 1 alumni are cool. Yeah. Woo.
