"(�) he started by ordering the monarch [D. Manuel I] to take off the fake emeralds out of respectfor the court and to hand over to the bailiff the pipe painted with the same yellow as the sceptre. Itwas then that I saw, for the first time in many years, the oakum locks from the wig of Your Honourand suddenly I realised the extreme emptiness of ordering the construction of more monumentson docks for world conquering caravels."(2)
António Lobo Antunes, As Naus
The Torre de Belém is certainly one of the monuments that best symbolizes the periodwhen Portugal's influence upon the World was at its peak, marked by important maritimediscoveries and the expansion of the kingdom. For centuries the territories of the Indicand the Atlantic gave Portugal unrivalled riches which immediately translated into anopulent life style, proudly exhibited by the privileged classes.
The Jewel of the Tagus (1), an installation designed specifically for the Torre de Belém, combines monumental architecture with jewellery, paradigmatic manifestations of thecountry's extraordinary wealth derived from the exploration and development ofoverseas territories at different times in the History of Portugal. The Jewel of the Tagusemerges, resting on the tower, on the façade opposite the Tagus river, like an enormousnecklace of yellow, green, red and blue nautical buoys,(3) inspired by the magnificentworks of the national baroque jewellery of the last quarter of the XVII century.(4)
The festive and jolly character of the event � the nomination of the Torre de Belém asone of the 7 Wonders of Portugal � highlighted by the obvious visual impact of theinstallation, resulting from its monumental scale and the contrast created by the use ofcolour and the neutral tone of stone, do not hide an intelligent thought exercise and acritical comment concerning the national ethos. The laborious and inventive operation of substituting the precious stones, mostly of a high monetary value, for ordinary buoys, together with the other associated signs that represent a luxurious past, also alludes tomoments when the nation faces impending sinking and decay, resulting from acontinuous endemic incapacity to take advantage of the conditions favourable to buildingsound foundations, capable of maintaining the country on a path towards realsustainable development.
