In the southwest medina quarter of Marrakesh across Jemaa el-Fnaa rests the red-stoned Koutoubia Mosque. The mosque is the largest mosque in the city as it measures 80 metres long and 60 metres wide. The minaret atop the mosque is made of sandstone and measures 77 metres high. The spire atop this minaret is embellished with four copper balls that decrease in size towards the top; a style which is unique to Morocco. Although entrance into the mosque is mainly reserved for worshippers, you can admire the distinct Moroccan architecture from Parc Lalla Hasna, located directly behind the mosque.
