By a hair's breadth, the village of Gitter would not even be an independent district today. The village was incorporated into Salzgitter-Bad in 1940, after the part of the district around the Gittertor road with its old and new businesses had already been assigned to Salzgitter-Bad in 1936. It was not until 1949 that Gitter regained its status as a district, but the Gittertor area still belongs to Salzgitter-Bad.
The Christ Church, built in 1846 on the site of an old church from the 12th century, forms the center of the old farming village. It is surprisingly large for a village of just under 500 inhabitants at the time.
As early as the 19th century, ore was mined around Salzgitter-Bad and Gitter in small tunnels or in open-cast mines. An ironworks was built and put into operation at Gittertor in 1869 by Emil Langen, which ceased operations just a few years later following the founder's fatal accident.
In 1937, the ore mines were taken over by Hermann-Göring Werke and several shafts were sunk close to the village, which were later combined to form the Georg pit/Georg combined mine and connected underground. Mining ceased in 1965.
In 1941, the skeleton of an ichthyosaur(Platypterygius hercynicus) was recovered from the Georg pit, which was prepared in Halle and is now the "star" of the geological collection of the Salder Castle Municipal Museum.
To the south-east of the village lies the Schäferstuhl, an area suitable for gliding. During the National Socialist era, a gliding school of the National Socialist Flying Corps (NSFK) was set up here and a prestigious building was erected, which changed its purpose several times after 1945. Today it houses the Elisabethstift, a youth welfare facility run by the Diakonie. The gliding site is used by the Schäferstuhl air sports association.
Relics of the Gitter can also be found in Salzgitter-Bad today: the residential building of the Garßenhof was moved to the Traditionsinsel in Salzgitter-Bad and has served as a bed house for the Hotel Ratskeller since 1980. The gate of the Garßenhof was built as an entrance to the old Vöppstedt cemetery.
A special feature in Gitter is the open-air museum, where old agricultural equipment can be seen.
