The Benfica support is loud and keeps going for the full ninety minutes. The release of the eagle before kick-off is one of the more distinctive moments in club football anywhere in Europe, and first-time visitors tend to remember it long after the final whistle. The atmosphere builds early, so arriving with time to spare is worthwhile. Bars around the ground fill up in the hours before kick-off with a mix of home supporters and travelling fans. Away supporters follow steward directions to their designated area and generally stay there throughout the match. Security checks are thorough, so arriving at least an hour early keeps things smooth on the way in.
