As I walked the porticoes of Bologna it wasn’t long before the quirky knobs and knockers that peered out from the heavy wooden doors caught my eye. I couldn’t help but notice the wide variety of door furniture adorning the city’s thresholds. As I passed by entrances and doorways small human faces peered silently at me; some serene some grimacing. Gaping keyholes awaiting heavy metal keys yawned at me. Ornate, detailed; plain, simple all shared the purposes of announcing a visitor. Gleaming brass reflected the sunlight or unpolished and dull faded into the wood. Take a look – do you have a favourite?
