shape of an eight-pointed star, possibly symbolizing the celestial heaven. On the north side of the courtyard is the Sala de Dos Hermanas ('Hall of Two Sisters'), so-called because of two large slabs of marble that form part of the pavement. Its original Arabic name was al-Qubba al-Kubrā (), suggesting it had a particular significance. The hall is covered by one of the most remarkable muqarnas domes in Islamic art. The muqarnas composition consists of at least 5000 prismatic pieces, unfolding from the central summit into sixteen miniature domes right above the level of the windows. To the north of the Sala de Dos Hermanas, and accessed through it, is the Mirador de Lindaraja, a small projecting room with double-arched windows on three sides which overlook the gardens below. The name Lindaraja is a corruption of Arabic 'Ayn Dar 'Aisha (). This small chamber has some of the most sophisticated carved stucco decoration in the Alhambra and retains original mosaic tilework that features very fine Arabic inscriptions. The room is also covered by a unique vault ceiling consisting of a wooden lattice shaped into an interlacing geometric motif and filled with pieces of coloured glass. Renaissance apartments and courtyards To the east of the Comares Palace and the Palace of the Lions is an area of Renaissance-style Christian additions dating primarily from the 16th century. Directly north of the Palace of the Lions is the Patio de Lindaraja (Lindaraja Courtyard), originally an open garden area but turned into a cloistered garden by the addition of new structures around it during the 16th century. The fountain at its center features a Baroque pedestal made in 1626 that supports a Nasrid marble basin installed here at the same time, although a replica now replaces the original basin which is kept at the Alhambra Museum. On the west and north sides of the courtyard, along the upper floors, are six rooms constructed for Charles V between 1528 and 1537, known as the Emperor's Chambers. The most interesting details of the rooms are a marble fireplace sculpted with the emperor's coat of arms and a ceiling of panels painted with pictures of fruits. The paintings were made around 1537 by Julio Aquiles and Alejandro Mayner. To the west of the Lindaraja Courtyard is the smaller Patio de la Reja ('Courtyard of the Queen'), located between the Emperor's Chambers and the Comares Tower. A gallery
