Free Observation Deck in Washington DC?! Old Post Office Museum

📍Old Post Office Museum This building was originally used as a US post office, but is now preserved as a museum!! The building was on the verge of being demolished, but it was saved. When you go inside, there are historical explanations like in a museum, and after you pass through, you can take the elevator twice to go up to the top of the tower. ✅ There are iron bars, but you can take pictures of the scenery by inserting your phone through the gap. ㅎㅎ #HongKongAirFlightEvent
