In 1660 Çelebi went to Kosovo and referred to the central part of the region as Arnavud (آرناوود) and noted that in Vushtrri its inhabitants were speakers of Albanian or Turkish and few spoke Bosnian.[18] The highlands around the Tetovo, Peja and Prizren areas Çelebi considered as being the "mountains of Arnavudluk".[18] Çelebi referred to the "mountains of Peja" as being in Arnavudluk (آرناوودلق) and considered the Ibar river that converged in Mitrovica as forming Kosovo's border with Bosnia.[18] He viewed the "Kılab" or Llapi river as having its source in Arnavudluk (Albania) and by extension the Sitnica as being part of that river.[18] Çelebi also included the central mountains of Kosovo within Arnavudluk.[18]
