After the construction of the Berlin Wall in 1961, border stations between East Berlin (regarded as East Germany's capital by the German Democratic Republic but unrecognized by the Western Allies) and the sectors controlled by those three Western Allies were created. Although there were few crossings at first, more sites were built over the wall's lifespan. Many East Germans crossed the wall illegally by climbing over it, sailing around it, or digging under it, while many others died while attempting to cross.
