Nowadays the Fortress is used for all of the most important Florentine exhibitions and fairs.
Built on three floors, the modern pavilion that is usually used for these events was designed by architect Pierluigi Spadolini and inaugurated in 1977.
Standing in the centre of the great square inside the Fortress, the Pavilion is surrounded by ancient buildings that are gradually being restored: the Theatrino Lorenese, the Palazzo delle Nazioni, the Arsenal.
