This is an ancient Liv village, known as Mustanumm is the last village in the south-easterly direction, and during the mid-20th century, just a few Livonians lived there.  Of 307 inhabitants in 1935, only 15 were Livonians.  At the beginning of the 19th century, there were six farms and a lagoon here, but at the end of the century there were 63 farms.  The valley of the Baķupīte River and the sea had remnants of pilings that provided evidence about a Medieval port.  Legends say that the sea robber Trommel had a castle on the left bank of the river during the 14th century.  Sailing ships were once built in the region, as well. Two locations of cultural and historical importance in Melnsils are the ancient cult location that is the Baķi castle hill, and the castle hill of a sea pirate Trommel.
