Trapa comes from the Latin term calcitrapa referring to a spiked iron ball used as an ancient weapon.
Trapa natans is an annual aquatic plant with a submerged flexuous stem that anchors into the mud and extends upward to the surface of the water.
Water chestnut is presently found on the Sassafras and Bird rivers of Maryland, and in a number of ponds including a non-tidal pond above Lloyds Creek and in Urieville Lake in Kent County, Maryland.
La Trapa is a property with great cultural and environmental interest, situated in the extreme south west of the Serra de Tramuntana mountain range, overlooking sa Dragonera island, in the municipality of Andratx.
Later, La Trapa passed through different hands and the buildings and terraces were extended, transforming them into a property dedicated to agriculture, until well into the XX century, when the property was abandoned and left to ruin.
As for a visit to La Trapa, as well as natural elements such as the cliffs, the vegetation and the birds, special attention should be paid to the buildings and their surroundings, the water drainage, the mill, the threshing area and the vantage viewpoint.
