History The first part of the name Isernhagen derives from the word Yser or Yserne which means 'iron'. In the middle ages ironstone was found in the lowlands of the river Wietze. It was smelted on-site and used as construction material. The ending Hagene or Hagen describes a piece of woodlands or fencing of crop lands, common to keep away animals from the farmland.

Arms The coat of arms was drafted by Walter Peitschmann. It was authorized by the district of Hannover on 9 January 1987.

Description of coat of arms: "Separated by the silver diagonal wavy bar, top right three silver lilies on red (2:1), bottom left four silver horseshoes each other overlaying on green background".

Explanation of coat of arms: The three lilies on red in the top right half, are taken from the coat of arms of the once residential Barons of Cramm and they are symbols for the three local congregations of the former joint municipality Kirchwarmbüchen. The four Bauernschaften (peasantries), in which horse breeding was predominant, are symbolized by the four horseshoes. In between meanders the silver band of the river Wietze, which connects all villages of the joint municipality.
