Definition: 26-country borderless EU zone. Tourists can stay 90 days total in any 180-day period.
The Schengen Area is a 1985 agreement that abolished border checks between most EU countries plus Iceland, Liechtenstein, Norway, Switzerland. Non-EU tourists (USA, Canada, Australia, etc.) get a single 'Schengen visa' valid for 90 days in any 180-day rolling window — not per country. Track your days carefully; overstaying carries a multi-year ban. Common workaround: split time between Schengen and non-Schengen (UK, Ireland, Croatia until 2023, Romania, Bulgaria).
