Surely you know the ducks of the Parque do Lago, but did you know that the Gaiás is home to tits, bats, frogs, redstarts, bumblebees or stag beetles? And that the common kestrel nests every year at the top of the Museum? With the start of spring, at the Cidade da Cultura we are joining in the celebrations for International Forest Day and World Water Day - 21st and 22nd March, respectively - with an interpretative walk through the green spaces of the forest to discover the fauna and flora that live there.
