This monument’s construction was ordered by the Town Hall, paying homage to Gago Coutinho and Sacadura Cabral, the two Portuguese aviators that did, for the first time, the air crossing of the Atlantic-South (Lisbon-Rio de Janeiro) on the single-motor hydroplane “Lusitânia”. The monument is represented by the armillary sphere on top and a stone basis with commemorative inscriptions. It is placed near the city centre, in a square also called “the aviators”.
