About Costa Diadema

Costa Diadema, nicknamed the Queen of the Mediterranean, entered service in 2014 as the flagship of the fleet's pre-LNG era. At 132,500 GT she was the largest ship ever built for Costa at the time, featuring a 500-metre seafront promenade wrapping the ship's exterior. She underwent a refurbishment in 2023 and remains one of Costa's premier ships for year-round Mediterranean sailing.
