To the northeast, Segarra, with its terrain so characteristic tossalenc populated 'almond trees and cereals, which impregnated most of the banks of the rivers' Ondara and Zion, between areas of Tarrega and Agramunt; Garrigues and la Conca of Barbera in the south, which heightened the relief they are strong and the slopes between the serpenteig Corb river and the vineyards and olive groves. To the west, the plaIn Urgell, watered and prosperous, whose waters come mainly around the area Bellpuig.
