"The" hall

"They walked out of the chamber, back across the hall and through a pair of double doors into the Great Hall.
Harry had never even imagined such a strange and splendid place." (J.K. Rowling, Harry Potter and the Philosopher's Stone, c. VII, The Sorting Hat).
E, in effetti, anche senza le candele sospese a mezz'aria e il soffitto di velluto nero trapunto di stelle, "the" hall (per eccellenza) ha un fascino incredibile, il fascino di Oxford.
