Nagold is a town in southwestern Germany, bordering the Northern Black Forest. It is located in the Landkreis (district) of Calw (Germany/Baden-Württemberg). Nagold is known for its ruined castle, Hohennagold Castle, and for its road viaduct. It takes its name from the river Nagold, which flows through the town. Nagold has a beautiful city centre where half-timbered houses and modern architecture meet each other. The following small villages belong to the district of Nagold: Emmingen, Gündringen, Hochdorf, Iselshausen, Mindersbach, Pfrondorf, Schietingen and Vollmaringen. History was probably settled as early as the early Stone Age: 2000 to 3000 BCE. With its fertile soil and mild climate in the low mountain ridge, the basin afforded ideal possibilities for settlement. Traces of early human occupation from the Hallstatt culture (700 to 450 BCE) have been found in the "Bächlen" area. The Celts were in the Nagold basin by the 6th and 5th centuries BCE. They were responsible for naming the river Nagold, meaning "flowing stretch of water". A Celtic royal burial mound (locally called Krautbühl) and signs of numerous settlements and graves have been found on and around Schlossberg. By the 1st century, the Romans had established two settlements in the basin. One of these settlements was unearthed in the 7th century during construction of Remigiuskirche. Stone walls from the remains were used in the Remigiuskirche foundation. The Alamanni expelled the Romans from the Nagold Basin around 260. They emphasized settlement of the valley, and expanded their territory. Around 700, the Franks conquered the Alamanni. The Remigiuskirche was built during this time, and it is assumed the Franks established a court in the area. Nagold became the administrative center of the region which extended from Bondorf to Kniebis. Small towns and settlements began to spring up around Nagold. Pfalzgraf Rudolf von Tübingen established Nagold as a city early in the 13th century in order to protect his holdings in the northern Black Forest. Through marriage in the year 1230, Nagold came under the control of the Grafen von Hohenberg, who sped up development of the city. By the end of the 13th century, Nagold was encircled with a wall, complete with moat and gate towers. Around 1350, the Plague devastated the population. Construction was begun on Marienkirche church in 1360. The church was razed in 1876–1877, but an original tower built in 1401 still stands on Turmstrasse street. In 1363 the Hohenbergs were
