The littoral north coast of Portugal, mainly in the area between Gaia and Ovar, has suffered from the onrush of the sea over densely populated areas with permanent buildings that have been massively built since the middle of the last century, having succeeded in breaking the balance of the original and beaches, dunes and surrounding green areas, which operated as a thermal and environmental protection element (Fig. 6.8).

Such circumstances have breached the thermal and environmental balance that the previous urban settlements enjoyed over the centuries, both by the careful choice of places of implantation and by the low urban and population density that they have been able to preserve and understand.

Espinho, a coastal city located in this latitude, was a reference case because it grew and developed over the original beach still in the late nineteenth century as a typical summer activity city, having at the beginning of the twentieth century suffered with the advancement of the sea, destroying great part of the original city, imposing later on the redesign of the rest of the city located to the east part and serving as a warning to the same kind of urban settlement of others costal Atlantic cities, mainly about the risk of instability of the coastline and the impetuosity and strength of nature (Figs. 6.9 and 6.10).
