Barcelona: Explore Barcelona with a Local Specialist who sets out the city’s shape from street level — the long run of Passeig de Gràcia, the sharp grid of the Eixample and the way the skyline shifts as the Sagrada Família comes into view. The route ties together the city’s Modernista detail and its ongoing architectural change.

Peñíscola: See Peñíscola’s 14th-century castle rising above the old town, set on a limestone headland that divides the shoreline.

Valencia: Get your bearings in Valencia’s Old City as your Travel Director points out the surviving medieval gateways and the street grid shaped by centuries of expansion.

Seville: Visit Seville Cathedral, completed in the 16th century and recognised as the largest Gothic cathedral in the world. Walk through its vast nave and chapels and view the Giralda, originally built as the minaret of the 12th-century Almohad mosque. The cathedral’s scale and layered construction show how the site developed from Islamic to Christian use.

Seville: Join a guided walk through the Santa Cruz quarter, following a street pattern shaped by Seville’s medieval Jewish community until the 14th century. You’ll navigate narrow lanes, enclosed courtyards and small plazas reflect the district’s earlier layout, with surviving architectural elements that point to the neighbourhood’s social and cultural history within the wider city.
