Tropical Botanic Garden
Time Out says
Created at the beginning of the 20th century, it started as a study location for agronomy and veterinary students that there could find tropical and subtropical species of Portuguese colonies. With over 500 species and subspecies, the garden is also the home of several freshwater turtles, herons, and peach fronted parakeets and it’s open to the public. A tip: buy a little box of Pastéis de Belém (the famous house is a 2-minute walk away) before going in.
