The Ka'bah (The Qibla of Muslims)

The Kaaba is a cuboid structure which is made of granite quarried from nearby hills. Standing upon a 250 cm (98 in) marble base that projects outwards about 35 cm (14 in), it is approximately 13.1 m (43 ft) high, with sides measuring 11.03 m (36.2 ft) by 12.86 m (42.2 ft). Inside the Kaaba, the floor is made of marble and limestone. The interior walls are clad with marble halfway to the roof. The marble is inset with Qur'anic inscriptions.
