A Jóia do Tejo [The Jewel of the Tagus], an installation designed specifically for the Torre de Belém, combines monumental architecture with jewellery, paradigmatic manifestations of the country’s extraordinary wealth derived from the exploration and development of overseas territories at different times in the History of Portugal. A Jóia do Tejo [The Jewel of the Tagus], emerges, resting on the tower, on the façade opposite the Tagus river, like an enormous necklace of yellow, green, red and blue nautical buoys, inspired by the magnificent works of the national baroque jewellery of the last quarter of the XVII century.
