Nules Bunkers, Military bunkers in Nules, Spain.

The Nules Bunkers are four separate concrete and stone-block fortifications beside the Camí del Cabeçol, where it crosses the AP-7. Each has a trapezoidal plan 15–18 m long and 3–3.30 m wide, with a semicircular lowered-vault roof and a circular machine-gun emplacement with one or two rifle galleries.

The four bunkers were built by the rebel side after the Republican counteroffensive of 8 August 1938 reached the Camí del Cabeçol, following the capture of Nules by the 83rd Infantry Division on 7–8 July 1938. They held the coastal plain between the town and its beach until the end of the war, despite a new Republican push on 7 November 1938 by the 53rd Division.

The name Camí del Cabeçol survives in the road the bunkers guarded, and the four structures stand as the most visible trace of the 1938 fighting in Nules. Stone blocks taken from the town's own sidewalks were built into the concrete, so the fortifications literally contain pieces of Nules. The site is protected as a bien de interés cultural.

The bunkers are accessible on foot and located close to the beach, making them easy to reach from the coastal area. Wear sturdy shoes as the ground around them can be uneven and sometimes overgrown with vegetation.

The stone blocks in the bunkers' walls were taken from the pavements of Nules, so the fortifications carry pieces of the town itself. Bunker 2 now stands on the eastern side of the AP-7, cut off from the other three by a motorway that did not exist in 1938.
