Immediately to the rear of the Anguri Bagh gardens is the Khas Mahal (Armgah-i-Mualla). This elegant, pillared, white marble building, painted with floral motifs, was Shah Jahan's private palace and its beauty is a reflection of Shah Jahan's love of beautifult things. Overlooking the Yamuna River, it is not surprising that it has views of the Taj Mahal. The building stands on a white marble plinth underneath which there is a two-storey building. One of the rooms of this underground building contains a gallows on which offenders "of the harem's chastity" were executed. Entry to this underground complex is not permitted. On either side of the Khas Mahal there are two exquisite pavilions which were apparently used by Shah Jahan's daughters, Jahan-Ara and Roshan-Ara. A beautiful building on top of a dark secret.
