Brtonigla ([needs Croatian IPA] Italian: Verteneglio; Venetian: Vertenejo) is a village and a municipality in the north-western part of Istria County, Croatia.

[4] Brtonigla/Verteneglio was formerly part of the municipality of Buje, which is immediately north, and is bordered to the south by the River Quieto.

Brtonigla was mentioned for the first time in 1234, with the ancient name Ortoneglo or Hortus Niger, i.e. black ground garden.

Vertenejo was part of the Serenissima Republic of Venice and then of the Austro-Hungarian Empire, with the brief parenthesis of the Napoleonic Kingdom of Italy.

After the First World War and then the Treaty of Rapallo, the village became part of Italy, a period in which Verteneglio knew its maximum demographic and economic development.
