During the second half of the 19th century, a vast British colony arrived in Aguilas, an important presence that still lingers. Many of the buildings and much of the infrastructure built by the British still stand, such as the British cemetery, the municipal annex, the Hornillo Pier facing the Isle of Fraile, and the old home of an English merchant located on that island. The minuscule island of Fraile, 100 meters off the coast, was owned by the Scottish banker John Gray, who sold it in 1910 to the British Army Lieutenant Colonel Alexander Borthwick, who in turn transferred ownership to his son Hugh, with the overt aim of exploiting its quarry.
