Praça Dom Pedro IV, traditionally known as Rossio, is the heart of Lisbon's Baixa district and has been the city's main meeting place, center of commerce, and public life since the 13th century. It's a vibrant, historic square with distinctive architecture that makes it a must-see for any visitor.

The fountain in Praça Dom Pedro IV (better known as Rossio Square) is actually a set of two monumental Baroque bronze fountains, located symmetrically at the north and south ends of the square.

The 25th of April Bridge is a suspension bridge in Lisbon, Portugal, very similar to San Francisco's Golden Gate Bridge. It crosses the Tagus River, connecting the capital to the city of Almada. Inaugurated in 1966 as the Salazar Bridge, it was renamed after the Carnation Revolution on April 25, 1974, in commemoration of the end of the dictatorship. It is a vital structure that carries both vehicles and trains.

The Arco da Rua Augusta is one of Lisbon's most iconic monuments, located at the southern entrance to Rua Augusta, right on Praça do Comércio, facing the Tagus River. This majestic triumphal arch was built to commemorate the city's reconstruction after the 1755 earthquake.

The Rossio Square Fountain, officially known as Praça Dom Pedro IV, is one of the most emblematic features of Lisbon's historic center, in the Baixa district. In reality, there isn't just one fountain, but two twin monumental fountains located at either end of the square, flanking the central column dedicated to Dom Pedro IV. These fountains were installed in 1889 over old water wells and manufactured in France, specifically at the Val d'Osne foundry.
