<p>Are you kidding? Cambridge or Oxford, of course. Hogwarts is modeled after Cambridge and Oxford. Oxbridge have the old buildings (not the fake “old” buildings of the Ivies --which were, we must admit, built to try to replicate Oxbridge). Plus, they have the different colleges as represented by Hogwart’s 4 houses. The large dining halls, the robes, the coats of arms for the various houses, etc.</p>
<p>This really should be obvious.</p>
