The Jama Masjid is a very large mosque in Delhi, India, also built by the Mughal ruler Shah Jahan. It's one of the biggest mosques in India and is a very important place for Muslims to pray. Its tall towers and big open courtyard are amazing to see. To keep the Jama Masjid safe, we need to take care of its old stone, make sure the buildings don't get damaged, and help people who visit understand how to respect this holy place.
