Etymology
The name Las Piedras (Spanish for "the stones") derives from the large rocks at a ford on the creek of the same name. At that point, the creek bed of stones and sand could be crossed even during high water, on the road connecting Montevideo with the countryside. Large rocks were also visible from the banks, and the place came to be known as Paso de Las Piedras ("Las Piedras Ford"). The creek, the surrounding area and the city that developed alongside the ford subsequently took the name Las Piedras.[4]
Geography
Territorial setting
Las Piedras forms a continuous urban area with La Paz, Progreso and 18 de Mayo within the Montevideo metropolitan area. These localities retain their own administrations and urban centres, although they are connected by urban expansion and the main transport infrastructure of the micro-region.[5]
El Colorado and Canelón Chico form part of the rural and productive surroundings of the city; territorial planning instruments distinguish them from Las Piedras' urban neighbourhoods.[6]
Relief and geology
The area surrounding the city is characterised by the presence of granite deposits, historically associated with local quarrying. Quarrying has influenced the regional landscape and coexists with urban, suburban and rural areas in and around Las Piedras.[7]
Hydrography and environment
Las Piedras Creek runs through the area surrounding the city and, along part of its course, forms the boundary between the departments of Canelones and Montevideo. It is a tributary of Colorado Creek, in the lower sub-basin of the Santa Lucía River.[8]
The department's territorial planning instruments identify pressures on the creek and its basin associated with urbanisation, drainage and a range of productive activities.[9]
History
According to the Historical Association of Las Piedras, the founding process of the present-day city began on 8 March 1744, when Luis de Sosa Mascareñas received a one-square-league plot of land as a donation.[10]
During the second half of the 18th century, a settlement associated with farms, a chapel and local businesses developed. A chapel dedicated to Saint Isidore the Laborer was established in 1765 and became a parish in 1780.[11]
The Battle of Las Piedras was fought nearby on 18 May 1811. Revolutionary forces led by José Gervasio Artigas defeated Spanish troops commanded by José Posadas. The victory was one of the first important successes of the revolution in the Banda Oriental and enabled an advance towards Montevideo.[12]
In 1838, the architect Carlos Zucchi formalised the urban layout, consisting of a central square and 49 blocks.[13]
The railway arrived on 1 January 1869, strengthening links with Montevideo and encouraging the town's economic and urban development. Las Piedras station was the first railway station outside the capital.[13] On 15 May 1925, Law No. 7,837 officially raised Las Piedras from the status of villa to that of city.[14]
During the 20th century, the metropolitan expansion of Montevideo, internal migration and land subdivision drove the growth of Las Piedras.[15]

Population
Economy
Las Piedras is part of the Montevideo metropolitan area and has been characterised as a commuter town. It nevertheless has its own economic activity, with industrial, logistics, institutional and service centres, as well as links to the productive rural area of Canelones.[18]
The city and its surroundings are closely associated with wine growing. The National Institute of Viticulture (Instituto Nacional de Vitivinicultura, INAVI) has its legal headquarters in the city.[19] Its own facilities, inaugurated in 2022, include administrative areas, laboratories, warehouses, an experimental winery and a vineyard.[20]

Horse racing is also part of the local economy. The Las Piedras Hippodrome is part of the Integrated National Turf System and hosts meetings and races involving owners, breeders, trainers, jockeys and related services.[21]
The Parque Tecnológico Canario operates on the site of the former Comargen meat-packing plant. It is intended for productive development, business location, training and the promotion of economic and cultural activities.[22] The park continues to host innovation and training activities linked, among other areas, to agri-food production, sustainable tourism, the circular economy and renewable energy.[23]
Las Piedras Shopping, inaugurated in 2017 on Bulevar del Bicentenario, is one of the principal shopping centres serving the city and its area of influence.[24]
