This green "Eye" is formed by a tall spiral staircase in a brick tower, reaching toward the bell inside the Lamberti Tower, Verona Italy. (You are looking upward into the bell tower:) By Davide Lombardi
How can I get one of these staircases in my dream house? Because it is awesome. Lonely Planet classified this bookshop as the third best bookshop in the world, Livraria Lello & Irmão in Porto, Portugal (by Ricardo Bevilaqua).
