5. Umayyad Mosque, Damascus, Syria
One of the world's oldest and most revered Islamic shrines, Damascus's Umayyad Mosque dates back to 715, less than a century after the Muslim faith first burst spectacularly into the world. The monumental building itself reflects the changing times in which it was built, adorned with Classical Roman-style Corinthian columns and Byzantine-style mosaics alongside the first of the great congregational courtyards which subsequently became the norm throughout the Islamic world.
Looming above the approach roads to Abu Dhabi like a vast wedding cake – with minarets – the Sheikh Zayed Mosque (completed 2007) offers a gigantic monument to the Muslim faith in a region now better known for its seven-star hotels, record-breaking skyscrapers and palm-shaped artificial islands.
Perhaps not surprisingly, Abu Dhabi's shiny new mega-mosque boasts its own string of record-breaking attractions: the world's largest carpet lives here, along with the planet's largest marble mosaic. Although it's the serene beauty of the overall conception, with vast expanses of lustrous marble and myriad dazzling domes shining snowy white in the fierce Gulf sunlight, which really lingers in the memory.
A majestic monument to India's great Mughal rulers, rising in stately splendour above the tangled labyrinth of hectic streets at the very heart of Old Delhi. Commissioned by Shah Jahan, creator of the Taj Mahal, the Jama Masjid remains an unequalled symbol of Islamic architecture in a largely Hindu country, with soaring minarets, delicate marble domes and a vast prayer hall – as well as peerless views across the teeming melée of the old city from its vast courtyard, raised high above the streets below.
8. Great Mosque of Samarra, Iraq
Some sixty miles north of Baghdad, the Great Mosque of Samarra is one of the oldest and most unusual in the Islamic world (although currently off limits to casual visitors, for obvious reasons). The world's biggest mosque when it was completed in 851, the building was largely destroyed during the Mongol invasion of 1278 save for its outer walls and unique minaret, the so-called Malwiya Tower, a remarkable conical structure 52m high wrapped in a spiral staircase, like a gigantic upended telescope rising surreally from the desert sands.
9. Mezquita, Cordoba, Spain
The most enduring reminder of Islam's centuries of rule in Western Europe, Cordoba's Mezquita was built on the site of an early Christian basilica following the Muslim conquest of Spain and finally completed in 987 – before being returned to use as a church in 1236.
A miniature Renaissance cathedral was unceremoniously shoehorned into the heart of the building during the sixteenth century, although this does little to mask the building's Islamic, quintessentially Moorish character, with its endless rows of jasper, onyx and marble pillars – "like palm trees in the oases of Syria" as one visitor described it – with red-and-white horseshoe arches and a dazzling mihrab.
10. Diyanet Center Mosque, Lanham, Maryland, USA
Opened in 2016, the Diyanet Center Mosque is one of the largest and certainly the most beautiful of the many mosques serving the USA's 3.3 million Muslims. Designed in classic Ottoman style, the mosque was part-funded by the Turkish government and was built with Turkish marble.
Opposition to the "mosquestrosity" (as its critics dubbed it) was considerable, but supporters hope that the building will provide a valuable symbol of religious tolerance and cultural diversity to the country at large – not least to the current incumbent of the White House, just 21km down the road.
