Fodor's Expert Review Passeig Arqueològic

A 1½-km (1-mile) circular path skirting the surviving section of the 3rd-century-BC Ibero-Roman ramparts, this walkway was built on even earlier walls of giant rocks. On the other side of the path is a glacis, a fortification added by English military engineers in 1707 during the War of the Spanish Succession. Look for the rusted bronze of Romulus and Remus.
