Approaching its half millennium of existence, Havana exhibits a great amount of exquisite ironworks that take visitors by surprise. Railings, window grilles, lamp holders, guardavecinos, guardacantones, nails, doorknockers, for example, are all part of the functional elements that enhance its architecture. Amano wishes to draw attention to these treasures that the city holds and which, at times, add an unexpected component to its beauty.
