Largo Necessidades, 58
This may not the Lisbon’s prettiest park, but it sure is one the most special because of the contrast with the neatness of the Belém district where it is located.
Abandoned buildings and broken paths scream out for maintenance, but this would just make it another boring “nice” park. Instead, there is an absolute atmosphere of tranquillity and calm — whilst the noise of the city can always be heard in the distance, the cats and birds seem unperturbed by it since they wander and fly around easily within extensive gardens that are obviously their home.
There are no facilities there, not even a coffee stand, but it’s a really nice place to picnic under the old trees if it’s hot.
