The palace was entered at the Bab ai Ghadur, renamed by Christians the Gate of the Seven Floors, which was located at
the eastern end of the Alhambra's southern wall circuit. A second entrance, Bab ai Shari'a, renamed the Gate of Justice,
stands to the western end of the same wall and is noteworthy for the caNing of
an outstretched hand in the keystone and an inscription above the portal of a key. Various interpretations have been made of these symbols, which are likely intended to legitimize the rulers' claims of authority. The palaces were decorated throughout with colored tile work on the floors and the walls atlower levels and elaborately caNed stucco on the yvalls at higher levels. These designs
combine geometric patterns with naturalist floral motifs into a highly developed style of
calligraphy wherein Koranic verse and poetry become a visual art. The elaborate forms seen on the palace walls are often stylized script mirrored and transformed into an angular or cuNaceous composition.
