Looking for a romantic spot to share a kiss at sunset in Puerto Madero? This is the place. The Bridge of Woman (or Puente de La Mujer) is a white, sinewy structure resembling a plane taking flight, which was designed by Santiago Calatrava, the Spanish architect famed for his unusual approach to public architecture. It was opened in 2001 and crosses Dique 3, or Port Area 3. Calatrava is said to have listened to tango music while designing the bridge and to have intended it to be an abstraction of a couple dancing. The name of the bridge also refers to the naming pattern of the district of Puerto Madero, where all the streets are named for important women -- the only major city in the world with such a neighborhood. A sign between docks 2 and 3 gives biographies of the women.
