I first gave everyone the basic popularity of the Hassan II Mosque. It was built in 1987. At that time, it cost more than 500 million US dollars. For Morocco at that time, it was poured out. The funds were mainly donated by people at home and abroad because of high morality. The beloved king had a dream, saying that Allah gave him the truth: God's throne should be built on the water, so the fundraising began to be established. The mosque can accommodate 100,000 people to pray. It is the third-largest mosque in the world, in Saudi Arabia. After the Arab Mecca and the Medina mosque. The Hassan II mosque opens its doors to Muslims all over the world. However, non-Muslims only have VIPs and special permission to enter the main hall. Muslims from all countries can enter at any time. Before entering the main hall, the guards will ask if they are Muslims. You can't get in without the Quran. The uniqueness of the Hassan II mosque is that one-third of its area is built on the sea to commemorate the Moroccan Arab ancestors from the sea.
