The earliest documents mentioning Arolsen date back to 1131 when anAugustinian nunnery was established there with the name of "Aroldessen". The nunnery was secularized in 1526 and in 1655 became the residence of the Counts (later Princes) ofWaldeck, who converted it into a stately home. It was torn down in 1710 and replaced with a new Baroque structure (1713–1728) byFriedrich Anton Ulrich, Prince of Waldeck and Pyrmont (1676–1728).
From 1918 to 1929 Arolsen was capital of theFree State of Waldeck-Pyrmont (after 1922: Free State of Waldeck), which was subsequently incorporated intoPrussia.
The town is governed by the town magistrate which is headed by the Mayor of Bad Arolsen. The incumbent Mayor is Jürgen van der Horst (Independent), first elected in 2007. His current six-year term is scheduled to end in 2025.
Bad Arolsen's civiccoat of arms might heraldically be described thus: In argent a nine-leaved oak tree vert with four acorns Or, before which an inescutcheon within which in Or a bar-topped letter "A" sable surmounted by a halved eight-pointed star sable.
The oak tree stands for the surrounding woods and indirectly the fresh air that Bad Arolsen is known for as a climatic spa. The inescutcheon shows the town's (original) initial, and the eight-pointed star of Waldeck.
The original arms were dropped in 1938 owing to a perceived reference toFreemasonry, which was not officially tolerated inNazi Germany. The charge in question was "God's Eye" – a triangle with the sun's rays shining out of it, such as may still be seen inBad Krozingen's civic coat of arms. Bad Arolsen's old arms showed the same inescutcheon over this, but "God's Eye" was replaced with an oak tree in 1938.[2]
Worthy of note is the town'sbaroque layout near the stately home. The street grid shows a chequered pattern that was typical of that time. It was originally planned to build a mirror-image layout to the stately home's east and west, but the plans were never fully carried out; after completing the developments west of the stately home, there was no money left to do the eastern part. Instead, the mirrored layout is illustrated by landscaping the area with trees and bushes. Some of the development's buildings are protected by law. Since 1999 there has been aGestaltungssatzung – or "design code" – in place to ensure the townscape's current form through collective protection.
The "Grosse Allee" or "Grand Avenue"
The Grosse Allee ("Grand Avenue") is a remarkable piece of city landscaping. It is a broad avenue running one mile from east to west lined by some 880 German oak trees in a six-line arrangement. Particularly during the warm months of spring, summer and fall it attracts scores of people strolling and enjoying the shady park-like atmosphere. The avenue was built in 1676 as a prestigious connecting way for the carriages between the "Residenzschloss" and the princely "Lustschloss", the latter having been torn down in the year 1725.
The baroque-styleSchloß Arolsen, originally belonging to the Princes of Waldeck-Pyrmont with its imposing construction was built between 1713 and 1728 by architect Julius Ludwig Rothweil. Of particular importance are the ceiling paintings by the Italian artist Carlo Ludovici Castelli, and the outstandingstucco works by Andrea Gallasini.

Of particular economic importance to the town was its role as a garrison. In 1994 the Belgian Army deactivated its garrison and left the town. On 17 December 2004, theBundeswehr deactivated its camp in Mengeringhausen.
Bad Arolsen is located on therailway line fromKassel toKorbach. Local public transport is also handled by buses of the North Hesse Transport Association (Nordhessischer Verkehrsverbund; NVV). The town is also served by the BRS (Busverkehr - Ruhr - Sieg) bus company.
Since 1946, Bad Arolsen has been headquarters to theInternational Tracing Service, an organization dedicated to finding missing civilians, typically lost to family and friends as a result of war or political unrest duringWorld War II. The institution was led and administered until December 2012 by theInternational Committee of the Red Cross and funded by theFederal Republic of Germany; it is now administered by the Federal Republic of Germany.
A venue for millions of documents related to the Nazi-attempted extermination of the Jewish people and others, the ITS[4] holds vast archives ofNazi-related documents. In April 2006, German justice ministerBrigitte Zypries announced that Germany would cooperate with theUnited States and allow survivors and historians ofthe Holocaust access to 47 million pages of documents, although an eleven-nation accord had to decide unanimously that this was to be done.[5] More than 12 million of the documents have now being digitally scanned and shared with research institutions around the world. The archive fully opened when France, Italy and Greece ratified changes to the access protocol. Information kept hidden from the public since its inception was finally opened to the public in November 2007.
