'New City on the Wine Route'; Palatine German: Naischdadt), formerly known as Neustadt an der Haardt, is a town in Rhineland-Palatinate, Germany.

The town itself lies in the western park of the Rhine-Neckar Metropolitan Region between the Haardt mountains, the eastern edge of the Palatinate Forest, and the western edge of the Upper Rhine Plain in the middle of the Palatinate wine region, an area that is around 10 km wide and 85 km long.

These quarters do not have any particular privileges and are not legally incorporated districts, although some voting precinct borders match part of the boundaries.

[3] In 1969 the villages of Diedesfeld, Geinsheim, Gimmeldingen, Haardt, Hambach, Königsbach, Lachen-Speyerdorf and Mußbach were incorporated into the borough, followed in 1974 by Duttweiler.

However, they vary only slightly and are very evenly distributed throughout the year; only 3% of the weather stations register lower seasonal variations in precipitation.

Just a few decades after its foundation in the early 13th century, Neustadt was granted town rights on 6 April 1275 based on those given to Speyer.

When Frederick III died in 1576, he left a clause in his will that his Lutheran son, Louis VI should not inherit the Ämter of Kaiserslautern and Neustadt, but that they should go instead to his Calvinist brother, John Casimir.

In 1578, Count Palatine John Casimir founded the Neustadt College that was named after him, the Casimirianum, because his Lutheran brother, Louis had cleared the university in Heidelberg of Calvinists; John Casimir was active as an advocate of the reformed faith and offered the exiled professors and students asylum.

When he moved to Heidelberg in 1583 in order to take over the regency for his still under-age son there after the death of the brother's reign, Neustadt's short time as a university seat ended.

Denominational disputes over the following century were no longer pursued purely by argument, but with weapons, and the Palatinate was invaded by one campaign after another.

When, in 1722, the state road to Mannheim, the new residence of the Elector had been built (today the B 38), in 1723 the northern town wall was pierced.

Following the seizure of the Left Bank of the Rhine during the French Revolution in 1797–98, Neustadt became just an insignificant administrative centre, the canton capital of the département of Donnersberg.

[5] However, Eisner failed to take notice of their concerns and despite his subsequent assertion that the Pfalz was an integral part of Bavaria, this indifference helped fuel separatist sentiment in the area.

It retained this function de facto until 1945, although in 1939 Kaiserslautern was nominated as the Gauhauptstadt ("capital of the Gau") and the state authorities, who were formed in 1940 from the Palatine and Saarland administrations in Speyer and Saarbrücken and were led by the Gauleiter in personal union, were also not based in Neustadt.

These new towns are typically differentiated by the rivers upon which they lie (e. g., Neustadt (Aisch)), the regions they are located in (e. g., Neustadt/Hessen) or, in this case, a peculiar distinctive feature – namely Weinstraße – "Wine Route."

The following venues are available for cultural events: the Saalbau as a theatre and concert hall, the restored Herrenhof Mußbach as a cultural centre, the open air stage in the grounds of Villa Böhm, the Kleinkunstbühne, die reblaus in the Catacombe Theatre, the Theater in der Kurve in Hambach and the historic Steinhäuser Hof as the home venue of Jazzclub NW.

There is a total of twelve nature reserves in the borough: Am Wolfsberg, Lochbusch-Königswiesen, Mußbacher Baggerweiher, Haardtrand–Am Häuselberg, Haardtrand–Berggewanne, Haardtrand–Am Wetterkreuz, Haardtrand–Im Erb, Haardtrand–Am Klausental, Haardtrand–Schloßberg, Haardtrand–Am Heidelberg, Haardtrand–Am Sonnenweg und Rehbachwiesen-Langwiesen.

In Neustadt, the artist, Gunter Demnig, has laid 41 so-called Stolpersteine, metal paving stones, in memory of the Jewish victims of Nazism.

The first Stolperstein was laid on 6 December 2002 in front of the Kurfürst Ruprecht Gymnasium in Landwehrstraße in memory of Karl Strauß, a former teacher at the school.

[10] On 10 March 2013 the Justice Minister for Rhineland-Palatinate, Jochen Hartloff, and Neustadt's Lord Mayor, Hans Georg Löffler, opened the memorial site to Nazi victims which had been established in the prison building of the old Turenne Barracks by a friends' association founded in 2009.

About 500 men from over 80 Palatine municipalities were detained here who, due to their political or religious activities, had fallen foul of the authorities.

The high point of the festival, which traditionally takes place at the end of September/beginning of October, is the largest Vintners' Parade in Germany.
