Our hotel was very close to this attraction, and so we walked by a few times. Even if it weren't so convenient, I would say it is worth exploring the area. The property/park at the front of the building is nice, with a Rodin 'The Thinker' sculpture. Palacio Barolo is very close by as well. We also watched a show, Piaf, at Teatro Liceo. This was an amazing experience. I really wanted to do the tour of the interior, and it was difficult to find reliable information (I common theme, I find, in South American countries). Even walking tour guides said we could do the tour. But eventually we found out that it was closed to tours during our visit due to construction.

Our hotel was in the area , a few minutes walking distance and this is a must see place in BA. Unfortunately we have been in BA only for 2 days so we couldn't enjoy the tour inside. Even form outside it's worth the view. Beautiful architecture, huge, outstanding. It's the Capital building, where the decisions and the laws are done.

We weren't able to tour the interior of the building, but it was worth the time that we spent enjoying a walk along Avenida de Mayo and enjoying our approach towards this imposing building. There are parks and plazas leading up to it, and we enjoyed seeing some of the other imposing buildings (like Palacio Barolo) that were also nearby. We were glad that we'd taken some time for an afternoon walk nearby.

The palace is in the Neoclassical style, primarily made of white marble, and has elaborately furnished interiors, especially in the Lost Steps Hall and the Blue Room. It was designed by the Italian architect Vittorio Meano in 1898 and completed by the Argentine architect Julio Dorma in 1906. Its weathered bronze-plated green dome is 260 feet in height and weighs 3,000 tons. On national holidays, it is illuminated. The main entrance, the Entrada de Honor ("Honor Entrance"), is exclusively used for ceremonial purposes. A barber shop used to be in the basement, but it has been demolished. The Senate offers free guided tours on Mondays, Tuesdays, Thursdays, and Fridays in English (12.30 pm) and Spanish (5.00 pm). The tours visit several rooms, including the chambers of both houses and the library. In front of the Congress Building is a statue of The Thinker looking away. TIP: The zero-kilometre mark next to the building; is where all of Argentina's National Highways start from. Please Tick the box below if you find this review helpful or exciting. Thank you

The building is huge, impressive and a great spot to take photos. Is the center building in Buenos Aires downtown - location where the downtown walking tours normally start. Great backdrop for sunset photos.
