The Boitaca Bridge began to be built in 1862, during the reign of King Luís I, as attested by the inscription on a tombstone placed there. Its name derives from the former owner of the land, the French master Diogo Boitaca or Boytac. Crossing a branch of the River Lena, which runs through the parish of Batalhão, it was part of an old royal route that connected Lisbon to Porto. The bridge, in revivalist and neo-Gothic style and tinged with yellow, is defined by a flat deck over six pointed arches, surrounded by buttresses, on which rise pinnacles. Between these elements, and contributing even more to the Gothic air of the monument, is the stone fence with quatrefoils.

The Sheep's Sink is an imposing natural cavity, named after the sink carved under a stalactite that, in the rainy months, pours out abundant water. In the past, this natural refuge served as a drinking trough for cattle.

Legend has it that the bears that once inhabited the Iberian Peninsula would drink water from the sinks that were naturally formed from the rock, which are still visible today. Today, the village of Pia do Urso, in the municipality of Batalha, is a popular spot for nature lovers and outdoor hikers. In this Sensory Ecopark, which is adapted for the visually impaired, you can have picnics, hike and discover some of the region's stories.
