The Kastriot Museum is located in the village of Sinë, in the Arras administrative unit, within the Municipality Dibër. The museum started to be built in 1982 and was first opened to the public in 1985. In the framework of the “Nationwide Year of Skanderbeg” (2018), it became possible to restore the Kastriot Museum, which has been declared a cultural monument of the category of II.

The Kastriot Museum, in the village of Sina of Dibra is located only 20 kilometers from the city of Peshkopi. In 1985, this area was defined by historians as the center of the Kastriot Principality and the birthplace of the Albanian national hero, Gjergj Kastriot Skanderbeg. For this, a museum was built in the village of Sinë e Poshtme in the same year.
The existence of the “Cape of Skanderbeg”, “Stones of Gjin”, as well as the finding of an inscription in stone during the excavations for plates, led to the construction of the museum, which in its composition has held a number of objects of fighters gathered among years.
