While the majestic, domed marble mausoleum is the most iconic aspect of the Taj Mahal, the complex itself encompasses an extensive area of 22.44 hectares (55.5 acres) and comprises a variety of architectural features and landscaped gardens. Surrounding the central tomb are subsidiary tombs, a sophisticated system of waterworks, and the small town of Taj Ganji to the south. Additionally, a 'moonlight garden' lies to the north of the River Yamuna, designed to enhance the ethereal quality of the monument.
