The massive minaret of the Hassan Mosque, dating from 1195, towers over Rabat, although the huge mosque itself was never entirely completed and was largely destroyed in an earthquake in 1755. The minaret is unusually sited at the centre of the mosque building, and was intended to be 262ft (80m) high, though it stands today at 164ft (50m). Each façade of the minaret is intricately patterned with different motifs on each face. Opposite the Hassan Mosque is the Mausoleum of Mohammed V, one of the great monuments of modern Morocco, inaugurated in 1967. The deceased king lies entombed in white onyx, surrounded by royal guards, and hundreds of Moroccans pay homage by filing through the mausoleum each day.
