Quinta da Foz Airstrip

The specific reason is not officially documented, as is common for small private airfields. However, evidence strongly suggests economic factors and a change in land use. The airstrip was located on a private farm estate ('Quinta'), and the land was likely repurposed for more profitable agricultural activities by the owner. The gradual decline and subsequent integration into farmland point away from a sudden event like an accident or regulatory shutdown.

The site is no longer an airfield and is completely non-operational. The land has been fully converted back to agricultural use. The former runway area is now overgrown, tilled, or used for crop cultivation, blending in with the surrounding fields. The building that once served as a hangar appears to be repurposed as a barn for storing agricultural equipment and materials.

Quinta da Foz was a private ultralight (ULM) airfield, designated with the national identifier PT-0129. Its significance was purely local, serving the recreational general aviation community in the Ribatejo region of Portugal. It primarily handled ultralight and light sport aircraft for private pilots, likely associated with a local club or the owner of the estate. It featured a single unpaved (dirt/grass) runway (approximately 450 meters long) and a small hangar. It had no history of commercial, military, or other large-scale operations.

There are no known plans or prospects for reopening the airstrip. Given that the land has been fully reclaimed for agriculture, the cost and regulatory hurdles to re-certify and rebuild the airfield would be substantial. The prospects for its return to aviation use are considered extremely low to non-existent.
