Perhaps you found your true love and would like to propose in a romantic, unforgettable way. If, after watching numerous black-and-white movies you still have no ideas, we have a suggestion.

Invite your loved one for a weekend in Lisbon. Without revealing your intentions, drive to the location in the photo in the end of the afternoon, an hour or two before sunset. Take a bouquet of flowers tied with a ribbon that has two pieces of lead (one to use and the other to keep as a memento). Each piece of lead should have your two initials carved.

Find the perfect moment to say: “When ancient Greeks made eternal vows, they threw a piece of lead in the ocean and promised to keep their vows until the lead floated. I want to do the same; I’ll love you until this lead floats.” Throw one of the pieces of lead in the ocean with a dramatic gesture. Take some beautiful photos and celebrate with some great Portuguese espumante.

The gazebo in the photo is part of the Casa do Gato Cinzento estate, located between the Consolação and the São Bernardino beach. It is private property, so please ask the caretaker permission to let you in.
