Conchillas (Spanish pronunciation: [konˈtʃiʝas], locally [konˈtʃiʒas, -ˈtʃiʃas]) is a small industrial town located within the Colonia Department, in southwestern Uruguay.

Walker's solution was a radical one: to construct quarries at Conchillas and to ship the stone across the River Plate to the new dock site.

As was typical practice for contractors and 'company towns', Evans issued their own currency of tokens, which were widely accepted in the surroundings and recognised as legal tender by the Uruguyan government.

[2][3] However, with the outbreak of the Second World War, Conchillas key infrastructure was sold to two Uruguayan entrepreneurs who introduced a series of modifications.

Today, the English influence that resulted from the arrival of numerous European settlers is mainly evident in the architecture of Conchillas rather than in the way of life of its inhabitants.
