The history of Cascais, one place at a time
Assembled from 13 dug tiles · 151 sourced records · last reviewed 20 September 2026
Cascais grew from scattered Roman farm estates into a chartered fishing town in 1364, then into King Luís I's chosen summer court from the 1870s, and finally into a coast of forts, shipwrecks and exiled royalty, its ground still carrying Visigothic graves, quarried walls and a fort disarmed within a year of its rebuilding.
These are the individual spots Strata has dug in Cascais — not a guide to the town, but a record of what happened on particular ground.
