Lello & Irmao in Porto, Portugal. The Top 10 Most Beautiful Bookstores in the World. It opened in 1906 and features stunning Art Deco woodwork, a stained glass ceiling, and ornate shelving with a dramatic staircase up the center of the store.
We love everything about this window-filled corner, not to mention the view. The picture window maximizes the view, while the double-hungs give ventilation. We also love the low built-in book cases that have function as window seats.
