About this place
Grutas de Lapas (the Lapas Caves) are a network of underground galleries and vertical shafts in the village of Lapas, about 2 km from central Torres Novas in the Santarém district of Portugal. The site has held public-interest heritage status (imóvel de interesse público) since 1943 and combines geology with archaeology.
What are the Lapas caves?
Despite the name, these are not natural karst caves. Researchers describe them as man-made: the galleries were cut into calcareous tufa, a soft stone quarried along the Almonda river terraces for building blocks. The passages run beneath the old houses of Lapas, so parts of the village sit directly above the labyrinth.
What were they used for?
The earliest use was probably residential or funerary. Archaeological work, including a 2016 university thesis, examines burial practices dating to the 4th and 3rd millennia BCE. In later centuries the chambers served as storage rooms, wine cellars and animal pens. One entrance square is still called Largo das Catacumbas, the Catacombs Square.
How do you get there?
Lapas lies right next to Torres Novas, so a drive or taxi from town takes only a few minutes. The main entrance is at Largo das Catacumbas, on Rua José Mota e Silva. Torres Novas has a station on the Lisbon–Porto railway line, and the village is a short local transfer away.
Can you visit?
Yes, but conditions vary. Some listings give daily hours of 9:00 to 18:00, while others say visits are by appointment. Check the current rules with the Torres Novas town hall (cm-torresnovas.pt) before you go. The municipality has worked on a project to open the caves to visitors, and Portugal's National Laboratory for Civil Engineering (LNEC) assessed the stability of the galleries and recommended measures for weaker spots. Wear sturdy shoes, bring a phone torch and take care underground.
What else is nearby?
Lapas belongs to the parish union of São Pedro (Torres Novas), Ribeira Branca and Lapas, home to just over 8,000 people in 2021 across 22 km². The historic centre of Torres Novas with its castle is close by, and the Almonda valley offers riverside walks.
