The name Lokvica was given to the village after small lokva or pools, which can be found in the village vicinity. On the east side of the village is Pečina, which had an observation post on the top and a shelter in the cave. Due to its position and a beautiful view from it, Italians called it “the eye of Karst”. The remains of prehistory pottery and human bones were excavated from the known 150 metre long cave Pečinka or Leopardja jama cave (Leopard’s cave) which is situated at the foothills of Pečina. In the sinkhole above the village is a more than 200 hundred-year-old renovated štirna Vrhi drage (above the valley of Draga) of 3 metres in diameter and 3.5 metres in depth. It is accessible on stone stairs that lead into it and encircled with a stone fence. During the Isonzo front (1915-1916) several Austro-Hungarian military settlements with barracks, military hospitals, caverns, etc. were built between Lokvica and Kostanjevica. An interesting sight is also a rock Borojevičev stol from which general Borojevič supponedly commanded his army. A part of the village is the hamlet Segeti that was an important supply centre of Austro-Hungarian army. Two brothers shepherds from Istria settled here 300 years ago. They started to cultivate the soil and to build houses. Later on they abandoned sheep breeding and lived only from cattle breeding and land cultivation. Now the hamlet has only three houses from which two are empty.
