Megalithic Monuments of Alcalar

The Megalithic Monuments of Alcalar (Portuguese: Monumentos Megalíticos de Alcalar) are a group of burial tombs that comprise a Calcolithic necropolis, located in the civil parish of Mexilhoeira Grande, municipality of Portimão, Portugal [1]. During the 3rd millennium BC, a 10 hectare stretch of land, located at the end of a once navigable part of the Torre River became the centre of settlement [1]. Around 18 different megalithic tombs were constructed in the surrounding hills, forming a necropolis using various building techniques over time [1]. The area is populated by a necropolis of various rectangular burial mounds and tholos (with chambers and corridors) [1].
