Sant Martí is a large community park, a quiet square under dense trees, made up of quite distinct spaces which demonstrate the successive stages of building it over ten years. The result is a wide, green area with lots of neighborhood facilities.
The largest part of the park is like an irregular-shaped triangle, completely covered in grass and full of sparse trees. There is little paving, only what is necessary for crossing the triangle from one end to the other or skirting around it and providing access from Ronda de Sant Martí.
