The Karachi Municipal Corporation Building is one of the city's grander civic survivors from the British period, with a clock tower and a formal stone facade that still project municipal confidence. In a city often experienced through traffic and sprawl, buildings like this help anchor the older centre.
You will usually appreciate it from outside rather than as a toured interior. Pair it with nearby colonial landmarks, markets and old-town streets to get a better sense of Karachi before the post-independence city expanded far beyond its original civic core.
