Altdorf is a municipality in the district of Böblingen in Baden-Württemberg in Germany.

The northern part has fields and meadows and it spreads on fertile clay soil.

But at the first mention from the Papal certificate from the year 1204 there it is called Alcdorf.

This could show that Altdorf was a Franconian military settlement at the Via Rheni in the past.

But still the real origin of the name can no longer be determined with certainty today.
