The original building intended as the residence of the Arte della Lana was erected in 1308, as attested by two Latin inscriptions on the fronts of the current building, incorporating an older tower of the Compiobbesi family, partly burnt down in 1284, after the expulsion of the family since they were
Ghibellines. In the following centuries, further rooms were built to expand the headquarters, due to the considerable public activity of the Arte. To allow easier access to the upper floors of the church of Orsanmichele, intended to house the new General Archive of private contracts and wills,
Cosimo I de' Medici decreed in 1569 the construction of a staircase with access from via Calimala which, following the side of the residence with a further leaning body, determined an aerial connection between the two buildings on via dell'Arte della Lana. The project was realized by
Bernardo Buontalenti. After the suppression of the guild in 1770, the building was already transformed into a tenement, and became a rectory of the church of Orsanmichele from 1772 on. Purchased in 1890 by the Municipality of Florence, it escaped the demolitions of the Renovation despite being deeply compromised, and was sold in 1903 to the
Dante Alighieri Society for public readings as an illustration of the
Divine Comedy. This promoted a complex restoration and reconstruction of the property, now isolated following the rehabilitation of the Mercato Vecchio area (1885-1895), in order to transform the ancient Compiobbesi tower into an architecture adhering to the idea that one had then of fourteenth-century Florence. Having examined various projects (among which the one in numerous and beautiful tables by the architect Cesare Spighi is kept in the Historical Archive of the Municipality) the works were then implemented in 1905 by the architect Enrico Lusini, who in any case had the merit (compared to other hypothesis) of leaving the door designed by Bernardo Buontalenti to the right of the main front of the building, albeit demolishing the sixteenth-century staircase and building a new one on the other side of the building, as well as giving "gloss and dignity to a building which previously was only called the keep". ==Citations==
