Russia–Ukraine barrier
The Russia–Ukraine barrier, also known as the Ukrainian Wall or the European Wall (Ukrainian: Європейський вал, romanized: Yevropeiskyi val), and officially called "Project Wall" (Ukrainian: Проєкт «Стіна», romanized: Proiekt "Stina") in Ukraine, is a fortified border barrier built on the Ukrainian side of the Russia–Ukraine border. Early construction began following the outbreak of the Russo-Ukrainian War in 2014, as the Ukrainian government sought to prevent any further incursions by Russia into Ukrainian territory following the Russian annexation of Crimea and the Russian-backed separatist uprising in the Donbas.
