population of Idstein grew considerably after World War II, when many refugees and displaced persons moved to Idstein. Minister Hans Usinger first built a (community center) and pursued from 1961 the building of a larger church. The was dynamited in 1963. The building of the new church began in 1963. It was consecrated, again to St. Martin, on 5 June 1965 by Bishop Wilhelm Kempf. On 1 January 2017, the parish became part of the larger St. Martin Idsteiner Land parish, which includes five other former parishes: Maria Königin in Niedernhausen, St. Nikolaus von Flüe in Idstein-Wörsdorf, St. Martha in Niedernhausen-Engenhahn, St. Michael in Niedernhausen-Oberjosbach and St. Thomas in Waldems. A service was held on 5 February by Wolfgang Rösch.
