Although it is known as the House of Dorotheus, it is actually a network of chambers linked together to form a residential complex. It was most likely owned by a large, wealthy family and was named after an inscription found on one of the interior walls that mentioned Dorotheus. The complex is made up of roughly 20 interconnected rooms. It is also notable for having several front terraces and small vegetable gardens that would have met the needs of the family who lived there. There is an ancient aqueduct carved into the rock that passes above the housing complex and can still be seen today. The aqueduct carried water from the Zurrabah water reservoir (which is today located near the Petra archaeological park building) to a cistern beside the Palace Tomb. It probably also served the needs of the family living in this complex, including irrigating the gardens, drinking, and household use. The presence of the house and aqueduct highlights the advanced engineering skills of the inhabitants and their ability to utilize natural resources effectively.
