Whenever I visit a foreign country, I would try to visit the post office there whenever possible to get some first day cover as memento.
Kantor Pos Medan, or Medan Post Office, is located along Jalan Balai Kota, Medan, across the City Hall. A great colonial building, it was built from 1909 to 1911. The structure is domed shape and it is decorated with stained glass windows and chandelier.
A beautiful architectural piece in Medan not to be missed. If you are a philately enthusiast, do pay a visit there for some philately products, perhaps?
