Nahr El Bared camp in northern Lebanon was one of the first refugee camps to be set up to provide shelter for the hundreds of thousands of Palestinian refugees who lost their homes, lands and livelihoods after the 1948 Arab-Israeli conflict. By the mid-1950s, UNRWA had replaced the tents with concrete shelters to give the refugees better protection from the harsh winters and hot summers.
