Where the Grutas de Lapas are
The caves lie beneath the village of Lapas, about 2 km from the city of Torres Novas. The galleries extend below older houses and streets, making the village setting part of the site’s character. The address is Rua José Mota e Silva (Largo das Catacumbas), 2350-124 Lapas.
For a trip from Entroncamento, the caves are about 7.5 km from Made Inn Entroncamento. The nearby city of Torres Novas also has the Villa Romana de Cardilio Roman ruins, a separate heritage visit to consider when planning time in the area.
What visitors encounter at the caves
Visitors encounter galleries cut into soft limestone known locally as tufo, or calcareous tufa. Only part of the larger network is accessible to visitors, so a visit covers a limited section rather than the full underground system.
The caves’ origin is uncertain. One proposed explanation is that the galleries began as an underground quarry for tufo; other theories suggest earlier use as shelter or extraction during the Roman period. Some sources say the galleries had been abandoned by the mid-18th century.
The village of Lapas is documented under that name in 1212, while the oldest archaeological traces reported from the caves date to the 15th century. The site is classified as an Imóvel de Interesse Público, a designation dated 18 August 1943.

A cave visit from Entroncamento
From Entroncamento, plan the cave visit around the opening period and any booking confirmation rather than assuming you can arrive at any time.
