One of the main thoroughfares in Zaragoza's city centre is Paseo de Sagasta. The Paseo Cullar is where the street stops after starting in the Plaza de Paraso.

The path that crossed the Huerva River from the Puerta de Santa Engracia to Torrero is where the Paseo de Sagasta got its start. Following the Sieges, the city started to grow along the route leading to Torrero. Around the river at the time, the road only had a few tiny factories and pleasure towers built. The Jesuit Colegio del Salvador and the Colegio del Sagrado Corazón, two significant educational institutions, as well as the Zaragoza bourgeoisie, started to settle in this region.

Beautiful modernist buildings and villas were constructed in the area after the first urban development project for the Paseo was approved in 1900. These include the Casa Juncosa (Sagasta, 11), designed by José de Yarza Echenique; the Casa Tetuerta (Sagasta, 13), designed by Juan Francisco Gómez Pulido; the residential house at no. 17, designed in 1903; and the house at no. 17, designed in 1903 by José de Yarza Echenique. Félix Navarro Pérez's No. 17 from 1903, Juan Francisco Gómez Pulido's Casa Corsini (Sagasta No. 19) from 1904, and Miguel Angel Navarro's Casa Palao from 1912.

Later, in 1936, Regino and José Borobio constructed the Confederación Hidrográfica del Ebro building, which is located at number 24 on the promenade and is registered with the Town Hall.

Throughout its lengthy history, the modern Paseo de Sagasta has gone under a number of names. Historically, and prior to urbanisation, it was known as Camino de Torrero because it connected the city's centre with the Torrero neighbourhood, which took its name from a Luna (Zaragoza)-born family that settled on property close to the cemetery. It was originally known as Paseo de Sagasta and changed to "Paseo de la Repblica" with the arrival of the Republic. However, in 1938, following the fascist uprising that sparked the Civil War, the coup plotters—who were victorious in Zaragoza—wanted to alter history by appropriating the names of streets, avenues, and avenues. In this instance, Mola was declared the winner, and Paseo del General Mola was mandated. Despite efforts to restore its original name of "Camino de Torrero," the boulevard was renamed Paseo de Sagasta after the dictatorship ended, with Franco dying of old age in his bed, and the following restoration of democracy.
