Saturday we spent in the city to see some landmarks. Of course we started in the center, where we saw the White House and had coffee in Starbucks.
Later we took the metro to the Pentagon, something I really wanted to see. It's a massive building, very big. We walked around it, and saw the reconstruction from the damages of September 11th.
From there we took a long walk back to the city, over the Memorial Bridge towards the Lincoln Memorial. We had dinner in Union Station, the big train station of Washington that has recently been renovated. Saw a beautiful exposition there with pictures by a famous photographer (I've forgotten his name) of the city.
