The Al-Muhdhar Mosque, named for the 14th-century Sufi scholar Umar al-Muhdhar, is the spiritual centre of Tarim. The square white-washed prayer hall is impressive in its own right, but it is the minaret that takes the breath away — a single soaring pillar of mud-brick rising over a town otherwise no more than two or three storeys high.
The minaret is best seen from a distance at sunset, when the low light catches the white plaster against the orange canyon walls behind. The mosque is in daily use; non-Muslim visitors should be respectful and avoid prayer times.
