Leonberg is a town in the German federal state of Baden-Württemberg about 10mi to the west of Stuttgart, the state capital. About 45,000 people live in Leonberg, making it the third-largest borough in the rural district (Landkreis) of Böblingen (after Sindelfingen and Böblingen to the south). Leonberg is most famous for its picturesque market square, the centuries-old annual horse market, its past role as seat of one of Württemberg's first parliaments, and the Pomeranzen Garden- Germany's only remaining terraced garden which dates back to the late Renaissance.
