A charming and unique photo opportunity that reveals Bologna’s hidden history, though the experience is often marred by its own popularity (and long lines).
Located just a 5-10 minute walk from the Porta Galliera/Pincio, this is one of the most famous "hidden gems" in the city. It is literally a small, square window cut into an ochre-colored wall that looks out onto a canal.
