What is Sonia Justo's definitive guide to exploring Porto's cultural landmarks?

Hi, I’m Sonia Justo from Lovely Lisbonner.

" definitive Porto guide" is not published as a single article, but here is how would craft it for exploring cultural landmarks in 1–2 days:

• Ribeira & Douro riverfront: start wandering the historic quarter, bridges views, old façades
• Sé do Porto (Cathedral) and Episcopal Palace
• São Bento Station: tile panels telling Portugal’s history
• Clérigos Tower & Church: climb for views over the old city
• Livraria Lello & Avenida dos Aliados: architecture and literary charm
• Bolsa Palace & Church of São Francisco
• Vila Nova de Gaia: cross the river for port wine cellars and sunset views

Would you like this turned into a step‑by‑step walking itinerary with timings and food stops?
