Martorell is a municipality located in the Baix Llobregat region, at the beginning of the northern area of the comarca, also known as the Montserratí, at the confluence of the Anoia River with the Llobregat, right at Llobregat Junction, where the river narrows, passing through the small gorge formed by the last foothills of the Ordal Mountains and the hill of Les Forques. This area also marks the boundary with Vallès Occidental.

The area mainly covers part of the Llobregat river plain and part of the Anoia, highly urbanized and industrialized zones, and rises slightly to the south along the foothills of the Ordal Mountains, up to the ridge of the Ataix range, where the remains of Rosanes and Rocafort castles are found.

The historic center of the town of Martorell is located almost at the southern end of the municipality, stretched between the Anoia River and the Torretes hills, reaching the confluence with the Llobregat, near the well-known Devil’s Bridge, and has been an almost obligatory passage since ancient times between Barcelona and parts of northern, southern, and western Catalonia.

Being part of the Llobregat Hub, it still serves today as an important passage for the country’s main transport routes, which has facilitated a significant population growth, with a whole new area on the other side of the Anoia River, especially developed during the second half of the 20th century. Between the historic center and the modern part, Martorell currently has over 28,772 inhabitants (2020), quadrupling its population since the mid-20th century.

Part of the municipality has over the years shifted from being mainly devoted to agricultural activity, especially vineyards and irrigated land, where some small patches still remain, to being occupied by the area’s strong industry. In the southern part of the municipality, we find slopes of pine forests and heath replacing the former holm oak groves, where in some corners of the north-facing streams, small patches of oaks and deciduous trees, such as elm and carob, can still be found.

The main festive events of Martorell are the Tres Tombs, normally celebrated on the first Sunday after Epiphany; the Ball of the Quadrilla, around Carnival; the Caramelles, at Easter; Sant Jordi, around April 23; the Spring Fair, the last weekend of April, celebrated since 1422; the PAS, Bridge to the Sound Arts, in summer; the Main Festival, in mid-August; the Roser Festival or Most Festival, the first weekend of October; the Santa Llúcia Fair, the Christmas Magic and the Three Kings Parade, during the Christmas season.
