The hill where the Castro is located called “Serra do Castelo” is under the village of Columbeira, Vila de Bombarral, District of Leiria, Central Portugal
 
Castro da Columbeira is located in Vale do Roto, close to the parish of Columbeira and in the municipality of Bombarral.

Castro da Columbeira is a prehistoric fortified settlement from the Chalcolithic period where you can see the lines of the wall, 6 turrets and the entrance to the central enclosure.

The fortification was discovered in 1962, and is thought to date back to the Chalcolithic period, situated in a privileged location from where you can see other important settlements at the time, such as São Mamede.

The Castro may have had a later occupation during the Bronze Age, little remains of the original settlement, and beyond the wall line, at least six turrets can be seen, at the top of a small hill called “Serra do Castelo” and the entrance to the central enclosure.

The Fortification from the Chalcolithic period is located on top of a hill known locally as the "Serra do Castelo", in the municipality of Bombarral, its ruins were discovered at the beginning of the 20th century, but excavations were only carried out at the site later.

The quadrangular fortification had two lines of walls, several bastions and was probably erected during the Copper Age, around the third millennium BC, later in the Bronze Age a tower was added.

The various finds made during the excavations include pieces of bronze, ceramics, arrowheads, flint blades, stone axes or bone utensils, traces of food that paint a picture of a society that already developed agricultural and pastoral activities.

The Fortification is an important Copper Age settlement around 4,000 years old, it has two belts of walls reinforced with towers, the central fortification is quadrangular in shape, has circular towers, semicircular bastions and an entrance facing southeast.

The hill where the “Castro” is located was discovered by José Leite de Vasconcellos in the first decade of the 20th century and dates back to the Copper Age, more precisely from the 3rd millennium BC.

The quadrangular fortification is made up of circular and semicircular bastions, with a small entrance corridor facing southeast.

Archaeological research also includes diverse faunal remains such as the presence of isolated teeth, phalanges, carpal and mesotarsal bones, remains of macroinvertebrates (fish, amphibians, reptiles, birds and micromammals).

This fortification includes the exploitation of faunal resources of terrestrial origin such as hunting, trapping, the use of fire for cooking and keeping livestock for food and survival.
