One of the most iconic buildings on BBD Bagh is the old post office with its central rotunda soaring nearly 40m around a statue of a lance-wielding mail runner. Stamps are still sold here although most postal transactions are in a building 100m further up Koilaghat St. Outside that is a philatelic bureau where you can get commemmorative issues or have them make you a sheet of ₹5 stamps made incorporating your own photo into the design (₹300).
