Issersheilingen with its 140 inhabitants, is the smallest of the four remaining Heilingen villages in the Unstrut-Hainich district. Centuries ago, there were a total of eight villages ending in -heilingen. Issersheilingen is a very old settlement. Finds in the area prove that people lived here long before Christ. Issersheilingen appears as a place name in 1279. In 1311 it becomes Yssersheilingen, until we finally read Issersheilingen in 1816. At 294 m above sea level, it is the highest village on the Heilinger mountain range.

At the edge of the village in the direction of Neunheilingen, you will notice a mound on the left, the "Hök", a burial mound. The village priest carried out excavations here as early as 1866. He declared the documentation of his work to be a contribution to the study of antiquity under the title "Das Heidengrab von Issersheilingen". The "Hök" is marked as a ground monument by an information board and is included in the seal of the municipality

The bakehouse is a gem in the community. It was built by the community in 1881 with a room-sized stone oven. Before and after reunification, it stood empty and was already scheduled for demolition. However, the community made efforts to preserve and renovate it. In 2008, the renovated bakehouse was inaugurated with the first bakehouse festival.
