These so-called street niches were introduced in the 17th century and are an architectural feature in Malta. They can be found in almost every corner in Valletta. Virgins and saints flood the city, but what made me curious is the devotion of the people. You will meet many people, of all types and status, which do the sign of the cross on themselves as they pass by every saint, and even stop to pray and then move on. They are very devout.
