The bridge linked Hirschhorn and Ersheim, which had been practically deserted centuries before; so as early as in the 1930s a few houses and a new school for Hirschhorn (which was enlarged in 1970) were built on the left bank. Hirschhorn since the Second World War When the Second World War ended, Hirschhorn had to accommodate large numbers of evacuees, and also expellees, mainly from Sudetenland. By the end of 1946, there were about 400 evacuees, and about 415 refugees. The lack of space in the town itself made it necessary to create a new residential area on the Ersheim side. The cultivated plots and orchards of the previous centuries had to give way to housing. By 1982, nearly 1,000 homes had been built there. Today more people live in Ersheim than in the old part of the town. In 1960 Hirschhorn was recognized as a climatic health resort (Luftkurort).
