a seaport of south-eastern Spain, in the province of Murcia, on the Mediterranean Sea, at the terminus of a railway from Huercal-Overa. Pop. (1900) 15,868. Aguilas is built on the landward side of a small peninsula, between two bays - the Puerto Ponente, a good harbour, on the south-west, and the Puerto Levanto, which is somewhat dangerous to shipping in rough weather, on the north-east. It is the chief outlet for the Spanish trade in esparto grass, and for the iron ore and other mineral products of the neighbourhood. It has also some trade in fruit and grain. The imports consist chiefly of coal. In 1904, 296 vessels, of 238,274 tons, cleared at this port.
