The State Bank Museum is one of Karachi's more unusual museums, using coins, notes, documents, and institutional history to tell the story of money and banking in the region. The subject sounds narrow, but in a trading city like Karachi it opens onto empire, partition, state-building, and commerce.
It is a good second-tier stop in the old financial district, especially for travellers who like museums with a specific angle. Combine it with nearby colonial-era buildings and markets to see how Karachi's commercial centre developed.
