The Combatentes underground station is located on the S Line of the Oporto Light Metro, and develops over a plaza near the junction of Rua da Alegria with the Av. dos Combatentes da Grande Guerra. This Station is located on a flat area with low population rate.

The station is composed of a main cavern where the railway platform is and a transversal gallery. The access shafts are delimited by a retaining structure comprising a secant pile cut off wall that confines the excavated area.

The main shaft has an approximate total length of 35 m and an inner width of about 21 m. The bottom slab is located at variable levels, with its deepest point at level (120.7). In order to reach that depth, it was necessary to carry out an excavation of approximately 27 m.
