Gedung PTPN XV is a Dutch colonial office building tied to the plantation economy that shaped Semarang's commercial history. It is still primarily an exterior stop, but the facade adds another layer to a city where old trading houses, company offices, and port infrastructure tell much of the story.
Treat it as part of an architectural walk rather than a stand-alone sight. The building is most interesting when you connect it with Semarang's wider colonial core and its role as a Java port city.
