'Eecher Plaz' means Eich square; its official name is Place Dargent.
It is named after François-Joseph Dargent (1805–1869), a pharmacist and politician born in Luxembourg City. From 1864 to 1869 he was mayor of the commune of Eich, which merged with Luxembourg City in 1920. He co-founded the Société des sciences médicales. The square has borne his name since 1925.
