This wallpaper is named after the Iberian peninsula’s longest river, the Tagus, which flows from the mountains of Spain into Portugal, emptying into the Atlantic Ocean near Lisbon. It’s a subtle, and understated, design featuring an unusual moire of vertical bands, and is inspired by a flowing river. The area was visited by Nina Campbell’s ancestor, Lieutenant Keightley, when he was an officer in the British army around 150 years ago.
