Hardheim is on the north-eastern edge of the Neckar-Odenwald district. We see the former granary from the year 1683. Here the grain was not only stored on intermediate floors, but also shifted again and again so that the grain didn't get moldy. Today the building is an event hall and the Erfatal Museum is housed on the upper floor. Opposite is the oldest building on the square, the so-called Marstallgebäude from 1550.
