Project for the façade of Santa Maria del Fiore by Ferdinando Lasinio, in ink and polychrome watercolour on paper, prepared in 1868 with modifications dated 1872. From left to right the plan, in 1:50 scale, shows the north side and front elevation (with Giotto's bell tower to the side) and a wall section of the facade.

This composition included a basilica-type silhouette of Tuscan neo-Gothic inspiration, clad in white and green squared marble and adorned with rampant galleries, trefoil arches, double and triple lancet windows, galleries, rose windows, niches, spiers and twisted columns. It’s also enriched by statues and bas-reliefs, mosaics and stained-glass windows with episodes from the life of the Virgin Mary and images of saints.

Ferdinando Lasinio began to study the question of the façade in 1865, in preparation for the third competition, but he failed to meet the deadline and was excluded. He made changes to the part of the crowning of the aisles and re-proposed his project in 1871 and 1883, although by this date the construction of the facade had already reached the top level.
