The Jardim das Artes, or Arts Garden, is just down the street from the Lisboa and Wynn, along the Avenida da Amizade. It is a few blocks long, an ends near the Handover Gifts Museum, and the Centro Cultural de Macau. It also runs perpendicular to the Carlos d'Assumpcao Park.
There was construction going on last time I was there, when these pictures were taken, so it may look a little different and have more to see now. There may not be enough for some to warrant a visit, but if you are walking in this direction, I recommend it, and it is a nice park and better than walking along the street. There is also a small playground.
If it has changed much, I'll try to get more pictures on our next trip to update this page.
