Seven giant letters which are part of the alphabet created by Joan Brossa to spell out the word Barcino (Roman name of Barcelona), the principal name of the Colonia Iulia Augusta Faventia Paterna Barcino, which was the origin of present-day Barcelona. The letters, six of them are made of bronze and one of aluminum, are bolted to the ground and make up a funny and original visual poem.

Although the letters spell out a single word, each one is a work of art in its own right, and as a whole they create an interplay with the perspective and their surroundings. Surroundings which are defined by the Cathedral, the Roman wall, and the reproduction of an archway from the Roman aqueduct, which begins to emerge next to the sculpture.
