Olhão, Cidade do Mar and Ria, has a lot to offer visitors. It stands out in the areas of fisheries and the canning industry but also in tourism and agriculture. The Ria Formosa, the Markets and the historic area are ex-libris.
The Municipal Markets of Olhão, one of the ex-libris of the city of Olhão, began to be built in 1912, being inaugurated four years later. They have been one of Olhão's illustrated postcards for almost a century and a must-visit place for tourists and residents.
They were built stealing space from the Ria, consolidating the buildings through a process known as pile drivers, with each of the buildings supported by eighty-eight stakes, connected to each other through brick masonry arches. It is a place to visit, for these and other reasons.
The Litoral constitutes the sub-zone with more recent materials, Quaternary or even Neogene. These deposits came to overlap with those of limestone and marl that make up the Southern Mesocenozoic Rim, presenting, by their youth, a slightly rugged relief helped by a platform still not much cut by the runoff.
The entire coastal area of ??the municipality of Olhão is part of the Ria Formosa Natural Park, one of the most important wetlands at European level, having been considered in 2004 by the International Union for the Conservation of Nature as a wetland of world interest. .
It extends to the municipalities of Loulé, Faro, Olhão, Tavira and Vila Real de Santo António, and covers an area of ??about 18400 hectares along 60 km of coastline, from Ancão to Manta Rota, including a wide variety of habitats: barrier islands, marshes, mud and sand banks, dunes, salt pans, fresh and brackish ponds, water courses, agricultural areas and forests.
In the municipality of Olhão, Ilha da Armona is part of the barrier island system of Ria Formosa, where the beaches of Fuseta Mar and Armona Mar stand out.
