One of the most striking features of the architecture of the place is that things don't fit together quite right anymore. Ceilings and walls meet at unexpected angles, and the doors have been prehung and in some cases reshaped to fit twisting and sagging frames. It is very likely that the interior spaces of Hogwarts bear similar signs of age. Also features a number of secret passageways and hiding holes. Hogwarts Castle is a wondrous, magical building with many towers and turrets. It is home to Hogwarts School of Witchcraft and Wizardry. If Muggles approach the castle, all they will see is a mouldering ruin with a sign warning them to keep out, that it's unsafe. Hogwarts is built in a forested area, directly next to a fairly large lake, in the highlands of Scotland. The main entrance to Hogwarts is a set of huge oak doors which face more or less toward the west. The lake is to the south of the castle. The forest is very large, and parts of it extend around to the west of the castle.
