About this place
Ajuntament de Molins de Rei is the town hall and seat of local government for Molins de Rei, a town on the Llobregat river within the Barcelona metropolitan area. Standing at the heart of the town, the building still serves its administrative purpose today and doubles as a landmark for anyone exploring the historic centre.
Where does the name Molins de Rei come from?
The name literally means "the king's mills" — molins for mills, rei for king. The settlement was founded in 1188 on the orders of Alfonso II, King of Aragon and Count of Barcelona, who had water mills built to harness the flow of the Llobregat. That founding episode is still reflected in the town's identity and in its long-standing ties to the river.
What role did the Requesens family play?
In 1430, King Alfonso V the Magnanimous granted Molins de Rei to the Requesens family, turning it into a barony. Galceran de Requesens and his successors built their own residence in the town, the Palau de Requesens, where the family spent long stretches of time. The palace remains one of the most recognisable historic buildings in Molins de Rei and is closely tied to local memory of the barony era.
Why did the Carles III bridge matter so much?
Between 1763 and 1767, the town built the bridge known as the Pont de Carles III. It turned Molins de Rei into a mandatory stopping point on the route between Madrid and Barcelona, cementing the town's strategic and commercial importance for generations. The flow of travellers and goods across the bridge shaped the growth of the town centre, where the town hall now stands.
What should visitors know about the town hall building itself?
The Ajuntament occupies a central position where the main routes through the historic centre converge. It combines its administrative role — the mayor and the town council work here — with a role as a reference point for both residents and visitors. Its proximity to landmarks such as the Palau de Requesens means a walk through central Molins de Rei naturally passes right by the town hall.
How does the town protect its heritage?
Molins de Rei runs a Special Plan for Historic and Architectural Heritage (Pla Especial del Patrimoni Històric i Arquitectònic) aimed at protecting the town's most significant buildings and public spaces. The plan covers both structures tied to the Requesens barony era and later, nineteenth- and twentieth-century additions to the town centre where the town hall sits.
