Largo da Pena Ventosa

This guide to Largo da Pena Ventosa in Porto starts with the wind that gives the square its name, then digs beneath the surrounding houses to an Iron Age hillfort and Porto's medieval defensive wall. It traces the Roman harbor of Cale into the name Portugal, and follows Dona Teresa's grant of this hill to a French bishop named Hugo, tasked with rebuilding its walls and raising a cathedral. Pause here and picture that granite outcrop long before any of these walls stood.
