Brothel
Brothels are locations which appear in Assassin's Creed II and are the homes of the courtesans. In Assassin's Creed II brothels are located in Florence, Venice and Monteriggioni and all of them appear to have a small rooftop gardens. The only purpose of these gardens seems to be to distinguish the brothels from other nearby buildings.
La Rosa Colta
The Rosa Colta (Breaking Rose) is a brothel located in the city of Florence and it's leader was Paola. It was founded in 1465 when Paola decided to help the women of the streets by giving them a home. It wasn't uncommon to see members of the Signoria visiting, and sometimes even members on the Medici family were seen there. In Assassin's Creed II it is a glyph location and is where Ezio Auditore was taught the ways of the courtesans.
