Pista da Barragem do Roxo

The closure appears to be due to abandonment and a lack of maintenance rather than a single specific event. Small, private, unpaved airfields like this often close for economic reasons, such as the high cost of upkeep, declining use by local pilots, or a change in ownership of the surrounding land. There is no evidence to suggest it was closed due to a major accident or for military conversion.

The site is completely abandoned and unusable for any aviation purposes. Satellite imagery confirms the dirt runway is heavily overgrown with vegetation and is no longer distinct from the surrounding terrain. The land has reverted to a natural state and is part of the landscape adjacent to the Roxo Dam reservoir. There are no remaining buildings or aviation infrastructure on site.

Pista da Barragem do Roxo was a small, private, unpaved airstrip with local, not national, significance. Its national identifier, PT-0080, indicates it was once officially registered within the Portuguese system for ultralight (ULM) or general aviation airfields. Its primary operations would have included:
- **Recreational Flying:** Used by local pilots with ultralight and light sport aircraft.
- **Agricultural Aviation:** Given its location in the rural Alentejo region next to a major reservoir (Roxo Dam) and vast farmlands, it was likely used for crop dusting or other agricultural support flights.
- **Utility/Support:** Potentially used for maintenance access or aerial surveys related to the Roxo Dam itself.
It was a basic facility with no significant infrastructure like terminals or paved taxiways.

There are no known official plans, proposals, or credible prospects for reopening the Pista da Barragem do Roxo. Re-establishing the airstrip would require significant private or public investment to clear the land, regrade the runway, and complete the modern certification process with Portugal's National Civil Aviation Authority (ANAC). Given the availability of other airfields in the region and the likely high cost, its reopening is considered highly improbable.
