The Aachen house apple , syn. Cornelis apple , is an old variety of cultivated apple . It is grown as an orchard and is considered worth preserving. The Aachen house apple is an old local variety from Aachen , which is mainly found in the south of Aachen from Raeren ( East Belgium ) to Breinig ( Münsterländchen , Butterländchen). It is a typical fruit variety from Aachen orchards with over 20 safe locations in the city of Aachen and a few in the region.
The variety was probably created around 1800 and was first described in 1816 by the pomologist Adrian Diel under the name Cornely's Striped House Apple . Diel obtained the fruit from Carl Cornely from Maire, Mayor of Rimburg near Aachen. He described the variety in 1844 in his work The Rhenish Orchard . A few years later, in 1875, the pomologist Johann Georg Conrad Oberdieck described the variety as 'Corneli's Hausapfel' in the Illustrirten Handbuch der Obstkunde . From 1915, the variety was named Aachen house apples on a list of apple varieties in the Rhenish rangerecommended for the districts of Aachen and Eupen. Decades later, the tree disappeared from the fruit tree nursery's list of offers. Today the tree is rarely found in gardens or orchards.
The variety 'Aachener Hausapfel' is currently listed on the Red List of endangered native crops in Germany . This Red List includes all species groups of indigenous useful plants and their varieties, local varieties and varieties that were adapted to local conditions in Germany and were of importance.
