Some people say and believe that the Mikhailovsky Castle (the Engineers' Castle) is a haunted place. The russian tsar (king) Pavel I was killed there. He was fond of mysticism and was interested in numbers. He thought that four was the most important number in his life. And that was right for him. He ruled for four years four months and 4 days and in lived in his castle only for forty days. This place is very popular now. A lot of people come here to see his ghost. People know that it is a nice ghost and nobody is afraid of him. Curators of this museum say good morning to the ghost and wish a good day.
