Cascais has spent centuries attracting royalty, spies, and sailors to its Atlantic shores. On this self-guided audio tour, you'll trace how a humble fishing village became Portugal's most elegant seaside resort, shaped by royal summers, maritime science, and wartime intrigue. The tour starts at Cascais train station, the gateway that opened this coastline to the world when the line arrived in 1889. From there, you'll follow the promenade past Ribeira Beach, where fishermen and royal bathers once shared the same sand, and into the historic center along the wave-patterned calçada portuguesa of Rua Frederico de Arouca. At Praça 5 de Outubro, you'll uncover a remarkable historical coincidence: the same date that ended the Portuguese monarchy also marks its founding in 1143. You'll go past the Casa das Histórias Paula Rego and along the marina before finishing at Forte de Santa Marta, where the still-active lighthouse has guided ships along this coast for centuries.
