Teck was a ducal castle in the kingdom of Württemberg, immediately to the north of the Swabian Jura and south of the town of Kirchheim unter Teck (now in the district of Esslingen). Burg Teck takes its name from the ridge, the Teckberg, 2,544 feet high, which it crowned. It was destroyed in the German Peasants' War (1525). The castle was reconstructed during the 19th and 20th centuries.
In 1863, the title "Prince of Teck" (German: Fürst von Teck) was conferred as a courtesy title by King William I of Württemberg upon the children of his cousin Duke Alexander of Württemberg (1804–85) by his morganatic marriage with Claudine Rhédey von Kis-Rhéde (1812–41), ennobled as countess of Hohenstein. In 1871, Prince Francis, the eldest son of Duke Alexander, was created Duke of Teck. His eldest son Adolphus (born 1868) was the holder of the title in 1910.
In 1889 an observation tower with a refuge shelter was built and inaugurated on 1 September 1889. In 1933 a hall was built near the tower called Mörike Hall. Since 6 June 1941 the buildings are owned by the Schwäbischer Albverein. From 1954-1955 the Mörikehalle became a restaurant with sleeping rooms. On 9 November 1999 the surroundings of the Teck became protected area (Naturschutzgebiet).
The most famous of the Teck family is considered to be Duke Francis's daughter, Mary of Teck, who was queen consort to King George V of the United Kingdom and Empress of India.
