Pagus Lomacensis

The Lomme gau or pagus, often referred to using Latin, Pagus Lomacensis, or German Lommegau, was an early Austrasian Frankish territorial division. The oldest Latin spellings were Laumensis or Lomensis. It included the city of Namur, and the region where the County of Namur later came to form in the 10th century.

In modern terms Lomme stretched from north to south in what is now central Wallonia in French-speaking Belgium. It corresponds roughly with the part of the modern Province of Namur which is west of the Meuse. It also stretched into what is now Walloon Brabant in the north, the Belgian Province of Hainaut in the west, and to the south, into what is now France.
