The long building of the Logge dei Tiratori, equipped with a portico and bordered by the church of Santa Maria dei Laici, was originally the seat of the hospital of Santa Maria, erected in 1326 on the initiative of the homonymous brotherhood. In 1505 other city hospitals joined it. The building thus took the name of "Spedal Grande" and remained active until 1628. On its facade there is a fresco with the Madonna among the SS. Pietro e Paolo of 1473, attributed to a pupil of Nelli.
 
Already in the mid-fifteenth century, the Arte della Lana aimed to build, above the hospital, a covered room to "pull" the clothes (that is, to dry the fabric, stretched so as to make it assume a specific length and width) . The tiratoio was built, after countless disputes, only at the beginning of the century. XVII becoming one of the very rare examples of pre-industrial architecture.

Perugia in 2014 to strengthen the activity already carried out over the years in the fields of art and culture.
