Dominating the crest of the College Hill neighborhood on the East Side, the campus of Brown University exudes Ivy League charm. University Hall , a 1770 brick edifice used as a barracks during the Revolutionary War, sits at its center. To explore the campus, start at the wrought-iron gates opening from the top of College St and make your way across the green toward Thayer St. Free tours of the campus leave five times daily on weekdays, and on Saturday morning from mid-September to mid-November, beginning from the Brown University Admissions Office .
