#1 Koutoubia Mosque (Marrakech)
The Koutoubia Mosque, built in the 12th century by the Almohads, towers over Marrakech with its 252-foot pink sandstone minaret. As the city's largest mosque, its name honors the booksellers who once gathered at its base. Admire the landmark from the lush gardens or historic esplanade. Non-Muslims cannot enter, but the site remains the city's spiritual beacon.
