🇺🇾 Uruguay · Thermal Litoral and the Uruguay River
Mercedes is one of the most charming cities of the Uruguayan litoral, overlooking the calm waters of the Negro River, very close to where it joins the Uruguay River. Capital of the department of Soriano, it's known as 'the city of flowers' for its well-kept gardens, its tree-lined squares and a cared-for setting that make it especially pleasant to stroll. Its peaceful pace and its intimate relationship with the river define its character.
The Negro River is the soul of Mercedes. Its promenade and its waterfront invite you to walk, cycle and enjoy the sunsets over the water, while the nearby Isla del Puerto —a natural park connected to the city by a bridge— offers beaches, camping and nature steps from the center. The city combines that riverside life with a historic core of quiet streets, its cathedral, period buildings and a cuisine tied to river fish and the litoral tradition.
In addition, Mercedes is an excellent base for exploring the region: a stone's throw away is Villa Soriano, considered the oldest town in Uruguay, and about 35 km away, Fray Bentos, with its Anglo Industrial Landscape declared a World Heritage Site by UNESCO. This guide covers the essentials of Mercedes with a practical and warm eye: what to see in the city and on the river, how to make the most of its natural and historical surroundings and how to combine it with the great attractions of the litoral.
Mercedes was born in the second half of the 18th century as a chapel and a small settlement on the Negro River, in an area tied to cattle-raising and to crossing the river. Founded around the dedication of Our Lady of Mercedes, from which it takes its name, the town developed as a crossing point and center of a rural region. Nearby Villa Soriano, on the other hand, is considered the oldest town in present-day Uruguay, with origins going back to the first colonial reductions and settlements on the Negro River. Over time, Mercedes consolidated as the capital of the department of Soriano and as one of the most important cities of the litoral, benefiting from river commerce, cattle-raising and the agriculture of the region. Its location on the Negro River, close to the confluence with the Uruguay River, made it a port and a communications hub of the west of the country. Over the course of the 19th and 20th centuries, the city grew with an urban care that earned it its fame as the 'city of flowers', with gardens, squares and a promenade that makes the most of its privileged relationship with the river. Today it's a quiet destination for domestic tourism, a base for discovering the Soriano and Río Negro litoral. The full story is on our history page.

Origins, formation and what the sources say.
Half an hour from Mercedes there's a town of dirt streets that disputes a greater title with it: that of being the oldest place in Uruguay. Villa Soriano, on the same Negro River, sinks its roots into a 17th-century indigenous reduction, when Mercedes didn't even exist. That closeness to the cradle of the country is no minor detail: it tells that this corner of the litoral, today peaceful and flowery, was one of the first settings where what would become the eastern nation began to take shape. Mercedes was born later, but it inherited that historical depth from the river that unites them.
The region where Mercedes stands today, on the bank of the Negro River and near its confluence with the Uruguay River, was inhabited and traveled since pre-Hispanic times by indigenous peoples. These groups made use of the wealth of the rivers —fish, birds, resources of the riverside woodland— and moved through a territory of meadows, woodland and watercourses that would later be the heart of the department of Soriano.
The Negro River, one of the main watercourses of present-day Uruguay, was always a route of communication and an axis of life in the region. Its mouth on the Uruguay River made this whole area a strategic point for navigation and contact between territories, long before the arrival of the Europeans.
With colonization, the region became part of the dynamics of cattle-raising and Hispanic settlements. It was precisely in this Negro River area that some of the first populated centers of what would become Uruguay arose, in particular Villa Soriano, considered the oldest town in the country, whose origins are linked to the first colonial reductions and settlements on the river.
Mercedes was born in the second half of the 18th century, around a chapel and a small settlement established on the bank of the Negro River. The religious dedication of Our Lady of Mercedes, to whom the founding chapel was dedicated, gave the town its name: from there comes the name 'Mercedes' that the city keeps to this day.
The settlement developed in an area of cattle-raising activity and river crossing, making the most of its strategic location. Like so many litoral towns, it grew as a crossing point, a center of a rural region and a meeting place for the inhabitants of the surrounding countryside. The presence of the Negro River was, from the start, a decisive factor for its growth and its riverside character.
Over time, Mercedes gained importance and population, consolidating as the main urban center of the region and, finally, as the capital of the department of Soriano when the country's political division was organized. From that chapel by the river thus arose one of the most characteristic and beloved cities of the Uruguayan litoral.
Over the course of the 19th century, Mercedes consolidated as the capital of the department of Soriano and as one of the most relevant cities of the western litoral of the country. Its location on the Negro River, close to the confluence with the Uruguay River, made it a port and a communications hub of western Uruguay, benefiting from the river commerce that circulated on these rivers.
The economy of the region revolved around cattle-raising and, progressively, agriculture, products that found in the river an outlet toward other markets. The port of Mercedes and the riverside activity energized the city, which grew in population, commerce and services over the course of the century, in tune with the development of the young Uruguayan State.
The area was also the scene of the political and military ups and downs of the 19th-century Uruguay, marked by the civil wars and national consolidation, in which the litoral and its rivers had an important role. Despite those swings, Mercedes maintained its growth and secured its role as head of an agricultural-cattle-raising department and as a reference riverside city.
Over the course of the 19th and 20th centuries, Mercedes developed an urban care that would end up defining its identity and its fame. The city committed to beautifying its public spaces with gardens, tree-lined squares, flower beds and a neat promenade that made the most of its privileged relationship with the Negro River. That care earned it the affectionate nickname of 'the city of flowers'.
The promenade and the waterfront became the heart of the social life of Mercedes, a riverside walk where the city looks out over the river and enjoys its sunsets. The Isla del Puerto, connected to the city by a bridge, added a natural space of beaches and recreation steps from the center, reinforcing the character of Mercedes as a city turned toward the river and nature.
This combination of urban care, gardens and riverside life set Mercedes apart among the litoral cities and consolidated it as a domestic tourism destination appreciated for its calm and its beauty. The peaceful and flowery profile of the city, far from the bustle, became its main calling card.
Today, Mercedes is a quiet and appealing destination of Uruguayan domestic tourism, which combines its riverside side with its historical heritage and its well-kept surroundings. The Negro River promenade, the Isla del Puerto with its beaches and camping, the historic center with its cathedral and the gardens that gave it fame make it an ideal city for a slow rest.
Its location also makes it an excellent base for exploring the region. A few kilometers away is Villa Soriano, the oldest town in the country, with its timeless charm; and about 35 km away, Fray Bentos, with its Anglo Industrial Landscape declared a World Heritage Site by UNESCO. Thus, Mercedes functions as a gateway to a circuit that brings together deep history, industrial heritage and riverside nature.
Sport fishing, boat trips, the cuisine tied to river fish and the peaceful life by the water complete the appeal of a city that keeps alive its identity as a flowery litoral capital. Mercedes represents, ultimately, the serene and riverside side of Uruguayan tourism, where the river, the gardens and history go hand in hand.
