Its most important historical event was the arrival in 1887 of the British company C.H. Walker&Co. to deal with the extraction and exports of sand destined to the construction of the port in Buenos Aires. This industry promoted the arrival of workers of different nationalities: British, Italian, Scotch, Greek, Bulgarian, Austrian, Vasque, Turkish, and German, who populated the town.

Today, the cemetery, a real artistic show in the mausoleums, stands as a witness of the extraordinary diversity.

The Historic Monuments, so declared in 1976, are the Conchillas Hotel and the houses of the first dwellers, which compose a group of eleven habitation buildings, 120 Mt. long each, with a meter thick stone walls, founded in either lime or mud, and painted yellow. The two-slope roofs are made of concave zinc and painted red.

The hotel, part of the Evans&Co. founded by the immigrant David Evans, was one of the most important businesses in Uruguay, so much so that the Government allowed them to mint their own money.

The Port of Conchillas, 5Km. from the urban area, is an important beach that still has vestiges of the splendor of those times.
