Centro de Educaçâo Ambiental de Marim , about 3 km (2 miles)
east of Olhão, is an environmental education centre. Its 60 ha (148 acres) of
dune and pinewoods are home to various sights, including a restored farmhouse, a
tidal mill, a centre for injured birds, as well as exhibitions and aquariums.
The web-footed Portuguese water dog, once much used by fishermen, has been bred
back from near-extinction here. At the eastern end of the park are Roman tanks
where fish was salted before being exported to the empire.
