Masjid-e-Tooba is one of Karachi's most recognisable modern mosques, famous for its broad white dome and almost column-free prayer hall. The design is simple from a distance but impressive in scale, especially when seen across the open courtyard.
It sits in Defence Housing Authority, away from the older colonial and port districts. Visit respectfully outside prayer times and treat it as a short architectural stop rather than a tourist site with formal interpretation.
