Fonte Luminosa
This monumental fountain was built from 1938 to 1948, when World War II raged across Europe but Portugal remained a neutral war-free country. It’s called “Luminous Fountain” because of a light show that takes place daily after the sun sets, until 9 pm. The water falls from an upper platform to a large basin, but also only at set times—during the light show in the evening, and at lunchtime, between noon and 3. In the water are four sculptures of mermaids and another showing Triton on horseback. On either side of the monument are stairs that take you to a terrace at the top, with views over the Avenidas Novas.
