Mnarja, or l-Imnarja (pronounced ''lim-nar-ya'') is one of the most important dates on the Maltese cultural calendar. Officially, it is a national festival dedicated to the feast of Saints Peter and Paul. Its roots can be traced back to the pagan Roman feast of ''Luminaria'' (literally, "the illumination"), when torches and bonfires lit up the early summer night of 29 June.
