The tour opens at the base of the equestrian statue in Plaza de Berenguer el Gran, where the guide introduces the Roman settlement of Barcino that preceded the modern city. Sections of the original Roman wall are visible from this vantage point, providing a tangible connection to the city's earliest history.

From Plaza del Angel, the group walks along Via Laietana and Carrer Argenteria to reach the Basilica of Santa Maria del Mar. The guide discusses the construction of this 14th-century church and its fictional portrayal in Ildefonso Falcones's novels, which have brought global attention to this corner of the Ribera.

The group pauses at the Fossar de les Moreres to learn about the significance of this memorial site before continuing to the Paseo del Born. This wide medieval street, once used for jousting and markets, now leads to the Centro Cultural El Born, which hosts various cultural events throughout the year.

Carrer Montcada is one of Barcelona's most architecturally rich streets, lined with medieval and Renaissance palaces built by the city's merchant elite. Highlights include the Palau Dalmases with its carved relief of Neptune's triumph, and the exterior of the Museo Picasso, which occupies a series of historic noble houses.

Near the end of the route, the group visits the exterior of the chapel of Marcús, one of the oldest surviving religious structures in Barcelona. The guide explains the charitable work of Bernat Marcús, who founded a hospital and cemetery in this area during the 12th century.

The tour concludes at Plaza de la Lana, located a short distance from the starting point, bringing the circular route to a natural close. The guide provides final context and recommendations for further exploration of the neighbourhood independently.
