Battles of Hill 705 in the Sierra de Pàndols Historical milestone · el Pinell de Brai, Terra Alta, Tarragona Image of el Pinell de Brai, not of the place itself.

On the height a monument to the combatants was raised half a century later. 1938 Photo: jordi domènech (CC BY-SA 3.0) What to see and do in el Pinell de Brai
