Lisbon has a wonderful offering of parks, gardens and outdoor spaces, and they are put to good use with this free live music festival. Every Friday and Sunday, from May to September, five different gardens (one a month) will host this event, making for a perfect Sunday afternoon lying on the grass enjoying Lisbon's sun and some great live music.
