The nation of Malta is an archipelago of 21 islands, the second largest being Gozo, home to the Citadel, an ancient fortified city within a city. Inside the walls you’ll find the Old Prison, where you can get a glimpse into some pretty grim prison-digs from centuries gone by. Covering the walls and floors is centuries of graffiti, etched-in proof that carving your initials and crude drawings go back long before “Kilroy was here.”
Known simply as "The Old Prison," it was an active jail beginning in the mid-16th century, originally run by the Crusades-era Knights of St. John. At the time it was used for knights who were a little more rowdy than the others, and their 5x10-foot block cells gave them some time to cool their heels, and apparently let off a little artistic steam.
Much of the graffiti relates to the knights and their symbols, including crosses, medallions known as the “Malta Cross,” and lots of plain-old hand prints, names and dates. There are also some intricate carvings of ships, some with multiple planks on the hulls. One theory is that the planks were used as a kind of calendar system for the prisoners, as a tally of their time served.
The Old prison was later controlled by the British after the Knights were kicked out of Malta, and it was in some use up until 1962 when it closed completely, eventually being meticulously restored for visitors to see.
Notable prisoners included Jean Parisot de La Valette, the founder of Malta's capital city of Valleta, who spent four months there in 1538. He was convicted of attacking a man, and he later went on to become the Grand Master of the Order of St. John. Not bad for an ex-convict.
