Curt Ruts
I think that there are few people who know about curt ruts. In fact curt ruts are not found in many countries. The Curt Ruts in Malta are special. In fact many scientists came to Malta to study them. However nothing is certain and nothing was concluded. Some say that they were done by Romans, others say that they were used by terrestrial persons. However something mysterious about them exists. In fact some of them finish at Dingli Cliffs. (Unfortunately I don't have a photo to show you this)
