I passed through Adolfo Suárez Madrid–Barajas Airport (MAD)

I passed through Adolfo Suárez Madrid–Barajas Airport in Madrid, Spain and I got to mint this pretty POAP! MAD Terminal 4 (T4), opened in 2006, is one of the largest airport terminals in the world (about 760,000 m² including its satellite), and features a driverless automated people mover to connect with the satellite building. This POAP was minted in Q4, 2025 as part of a campaign to offer precious collectibles to travellers at 18 airports around the world.
