This is the oldest and most traditional spot in Lima. In fact, this is the place where Spanish conquistador Francisco Pizarro founded Lima; the first streets built here were the ones surrounding it. It houses the oldest and the most authentic monument in the city, that it, the brass fountain, placed there in 1651. The fountain and the Plaza as well have both survived through earthquakes, social revolts and urban development. Here you will find some very important and historical buildings like the Cathedral, the Archbishopric Palace, the Municipality and the Government Palace. The Official Act of Independence of Peru was proclaimed here, in1821, and the first bullfighting events were also held here. Another interesting spots nearby are the Casa del Oidor, the and very specially the Casa de Aliaga, property of the descendants of one of Lima first founders, still very well preserved. A must-see in your city tour.
