This is one of the most prestigious schools in England. Oundle School may be near the bottom of our list of best boarding schools in the world in 2017, but it is definitely the oldest. 1556 is the year of its foundation, and no one can top that. However, it’s a bit crowded in comparison to the rest. Oundle School offers education to 1,100 students.
