The Roman Villa of Can Llauder is one of the best-preserved Roman sites in Catalonia. The villa dates from the first century AD and was the centre of a prosperous agricultural estate — the Roman town of Iluro (modern Mataró) was the administrative heart of the Maresme coast, and wealthy Romans built extensively here.
The highlight is the mosaic floors in the reception rooms, which have survived with their geometric and figurative patterns largely intact. The site museum provides context on the villa's layout and the Roman occupation of the Maresme, with finds recovered during excavation. The site is managed by the Mataró Museum.
