The Badshahi Mosque is located in Lahore, Pakistan. It was built under the supervision of Mughal Emperor Aurangzeb from 1671 to 1673, taking two years to complete. The mosque has an architectural style that mixes different cultural influences, with red stone on the exterior, four white marble domes, and Islamic calligraphy decorating the interior walls and roof. As one of the largest mosques in the world, it was able to accommodate up to 100,000 worshippers and was considered the largest mosque globally for over 300 years until the construction of the Faisal Mosque in Islamabad.
