Many of the original buildings of the Avenue have been demolished in the last decades and replaced by modern office and hotel buildings. Nowadays, it boasts several interesting buildings that reflect Portuguese architecture from the late 19th through the early 21st centuries. Its pedestrian sidewalks and roundabouts, paved with the traditional Portuguese pavement, are decorated with many monuments and statues that pay hommage to important personalities like Almeida Garrett, Alexandre Herculano and others. The large monument to the fallen in World War I, inaugurated in 1931, is the work of Rebelo de Andrade and Maximiano Alves.
