It is very close to Linz and offers a beautiful view of the Alps and therefore attracts the upper social classes for living without providing much infrastructure on its own. Due to the proximity of Linz and the good transport connection (like West railway, Westautobahn, B1 Wiener Straße or Linz Airport) it attracts companies like Rosenbauer, Ebner Industrieofenbau, Poloplast or Neuson. Another major employer is the UNO Shopping Center (approximately 850 jobs).
From 1898 to 1905 Adolf Hitler lived in Leonding where he attended the local primary school and later a grammar school in nearby Linz. The graves of his parents Alois and Klara are in Leonding. His brother Edmund, who died of measles, was buried there, too. A delegation of Passau National Socialists visited the family's grave illegally. Hitler visited the grave in 1938. In 2012, when a relative of Alois Hitler's first wife, Anna, did not renew the lease, the grave was dissolved.
In 1903, Hitler's father died when drinking a glass of wine in a bar in Leonding.
