Religion plays a significant role in the culture of Dubai. Mosques can be found throughout the city and at sunset the call to prayer can be heard across the rooftops. It is possible for non-Muslim tourists to visit certain mosques in Dubai; perhaps the most impressive is the Jumeirah Mosque, tours of which can be booked through the Sheikh Mohammed Centre for Cultural Understanding. Ramadan is a popular time of year to visit Dubai; although all residents and visitors must refrain from eating or drinking in public in daylight hours, it is a wonderful time to experience the local culture and strong religious heritage of the city. Non-Muslims may eat and drink in designated areas, and many hotels and shopping malls will have various outlets that remain open during Ramadan.
