Setting and Nostalgia in Contemporary Narrative

Consider the following passage from a contemporary narrative:

The old library stood in stark contrast to the modern architecture surrounding it, its weathered stone facade radiating stories of the past. Inside, the scent of aged paper and leather bound volumes filled the air, and the dim lighting cast shadows on rows of books that whispered secrets of forgotten times. A solitary figure sat at a wooden table, surrounded by the muted rustle of turning pages, immersed in a world where time seemed to stand still.

Based on this excerpt, which aspect of the setting most effectively enhances the theme of nostalgia?
