CAIRO (REUTERS).- The world’s biggest museum of Islamic art will reopen in Cairo in coming weeks after a seven-year facelift, museum officials said on Wednesday. Tourists flock by the millions to the Pyramids at Giza and the Temples of Luxor dating back more than 3,000 years but the wealth of art and design heralded by the arrival of Islam to Egypt in the 7th century tends to take second place. Before it closed in 2003, only a few thousand curious travellers were venturing each month into the museum, set by a noisy road in the heart of Egypt’s frenetic capital. The building designed by Italian Alfonso Manescalo dated from the early 20th century and was jammed with some 3,000 treasures, many poorly labeled, including ceramics, tombs, doors, wooden screens, robes and rugs. Its walls were showing cracks because of earth tremors. During the closure, a rival museum of Islamic art opened in the Gulf state of Qatar designed by celebrated Chinese-American architect I.M. Pei.
