Aßlar lies in the foothills of theWesterwald range and on the riverDill, which empties into theLahn in neighbouring Wetzlar, about 5 km to the southeast. It is also not far from the "three-state-border", a geographical point common to the German states ofHesse,North Rhine-Westphalia andRhineland-Palatinate, lying to the west.
The Aßlar community of Werdorf also lies on the River Dill, as do Klein-Altenstädten and Berghausen. Bechlingen, Oberlemp and Bermoll lie north of the main town, away from the river.
Aßlar is divided into the following communities orStadtteile:
Aßlar with Klein-Altenstädten
Bechlingen
Berghausen
Bermoll
Oberlemp
Werdorf
The communities of Werdorf and Berghausen are so near each other that they merge one into the other, but are officially twoStadtteile, which may be considered "wards" or possibly "boroughs".
Aßlar was first mentioned in A.D. 783 in a charter of an ecclesiastical grant copied into theLorsch Codex (orCodex Laureshamensis inLatin).
Like many other places, Aßlar grew from a few great estates to about 5,000 by the time of theFirst World War, always forming a community with Klein-Altenstädten on the other side of the River Dill. Following theSecond World War, a great number of refugees settled in the area from various lost German territories. The municipal reforms of 1977 led to its amalgamation with Bechlingen, Berghausen, Bermoll, Oberlemp and Werdorf to produce today's town of Aßlar.
In theBronze Age, people settled on the Schönbach, which flowed through the area, as this stream was more easily forded than the broader River Dill. Werdorf was first mentioned in the historical record in A.D. 772.
"Werdorf" comes from an Old Germanic root "Wero", meaning "man". This root is common to manyGermanic languages, and can also be seen in theEnglish words "wergild" and "werewolf".Dorf is still theGerman word for a village, and has cognates in other Germanic languages, including "thorp" in English.
Tradition tells of alegend recounting how Werdorf got its name, namely:
There were once two countesses who were riding together along the Dill, when they found a place they rather liked, and they had a stately home built there. Since now the workmen were living here, one countess said "May it become a town!". The other answered "No, may it become a village!" (in German: "Nein, es werde ein Dorf!")
Approval to bear acoat of arms and aflag was granted to the town in 1959 and 1960 by the Hessian government. The colors and heraldic composition of the arms, appear to originate with the Counts ofSolms and the Lords of Bicken who are represented by the lion and the lozenge. They were the chief medieval noble families of the surrounding area. Thehazelnut refers to that interpretation of the town's name, which derives it from the word "Haselare", where "Hasel" in "hazel" in German. This word was used in early medieval times for a sacred place separated from the profane by an enclosure of hazel rods. This sacred place was later appropriated by the local Christian bishop and achurch was constructed on the site, which is still there today, and where Christian worship is conducted weekly.
Aßlar is today a small industrial town with well-developed infrastructure, where the firmsPfeiffer Vacuum andManfred Huck are established. The latter has its head office in Berghausen for the manufacture of quality nets and rope for sport, industry and education.
