The Tapada das Necessidades is ten hectares of walled ground inside the city that nobody has taken in hand for a century. The paths are dirt, the lake is green and half-choked, and the planting has simply gone on growing. In the middle of it stands the wreck of a glasshouse: most of its glass is gone, and plants push through the iron frame. Peacocks have the run of the place.
It has not been restored, and there is no sign that it will be. The estate was a walled enclosure attached to the Necessidades palace, kept for one family's own use, and it lost that use in 1910. Nothing has been decided for it since. The neighbourhood behaves as if it were a park, which is what it has become: dogs, runners, people reading on the grass, teenagers on the wall. The palace is government offices and closed, so the grounds are the part you can walk in.
