The crème frites, that is supposedly a Venetian traditional dessert, was possibly first invented by nuns who sold them to support their convents.
This is a typical street food that is very popular in Italy as well as Spain (where they claim to have invented it).
Until the 9th century, most of the buildings in Venice were only two stories high, however over the years, as more and more people came to settle in the city, they had to add more floors to their houses.
The Medico della peste long beak design was actually developed by a doctor physician named Charles de Lorme in the 17th century in order to prevent the spread of the plague disease.
Now, during the Carnival of Venice, you will see many of the people on the streets wearing this particular bizarre mask with many designs and decorations added.
