forced out of Nagold, and the Dukes Eberhard and Ulrich von Württemberg bought the city. Nagold then served as a court city (Amtstadt), and in 1806 was elevated to a high court city (Oberamtstadt), which lasted until being abolished in 1938. In the 16th century, farmers' uprisings led to the departure of the local aristocracy. Austria, always looking to expand the Habsburg domain, quickly moved into the Nagold area. Herzog Ulrich reclaimed his lands in 1534, and embraced Protestantism. During the Thirty Years' War (1618–1647), the Burg Hohennagold (castle) was destroyed. Parts of Nagold were destroyed in devastating fires in 1825, 1850, 1887, and 1893. Marktstrasse is one of the few streets in Nagold to have escaped destruction in the fires. A large of portion of the architecture on this street dates to the 18th century, and includes the three-story Rathaus (1756–1758), the Stadtbrunnen (city fountain), the Schmidsche Apotheke with rich ornamentation, and numerous Fachwerk (timbered) houses from the 17th century. Other architectural treasures are scattered through the city. Among these are the Alte Schule (old school, 1706) and the Alte Vogtei with Celtic origins. The hotel "Alte Post" (1699) served as a stop on the old mail line between Stuttgart and Strasbourg. The Oberamtei (from 14th century) is located on Oberamteistrasse, and was the location of the high court (Oberamt) from 1812 until 1938. As early as 1924, Nagold was a NSDAP (Nazi) base of support. According to voting statistics, 19.4% of the population voted NSDAP in May 1924. Comparatively, the NSDAP captured just 6.5% of the vote nationwide, and a mere 4.1% in Baden and Württemberg during the same election. The Reunification of Germany in 1989 brought new hopes for the future of Germany and Nagold, but was quickly followed by the worst recession in post-war history. Home construction, attraction of industry, and improvement of infrastructure have been difficult problems for Nagold. A city policy of construction, combined with improvement of the old city center, are cornerstones of the city planning. In 1992, the city's open-air swimming pool was amended with an indoor pool, and in 1996 a new cultural center named "Kubus" was built in the city center.
