Pista de Almoster

No official reason for the closure has been publicly released. As a small, private ultralight (ULM) airfield, it was not a public facility. Closures of such airfields are typically due to private reasons, such as the owner ceasing operations, financial non-viability, sale of the land for other purposes (like agriculture), or non-compliance with evolving aviation regulations. There is no evidence of a major accident or military conversion leading to its closure.

The site is abandoned as an airfield. Current satellite imagery shows the dirt/grass runway is still faintly visible but is completely overgrown with vegetation and unusable for any aviation activity. The land appears to have reverted to a state of nature or is being used for passive agriculture. The associated hangar-like buildings are still present but their current condition and use are unknown; they are likely derelict or used for farm storage.

Pista de Almoster was a local, private airfield primarily serving the recreational ultralight (ULM) and general aviation community in the Santarém district. Its significance was not national or military, but rather as a hub for local aviation enthusiasts. It operated as a base for private pilots to store, maintain, and fly their light aircraft. Satellite imagery from its active period (e.g., 2011) confirms the presence of small aircraft and hangar facilities on site.

There are no known or published plans or prospects for reopening the Pista de Almoster. Re-establishing it as an active airfield would require significant investment from a private owner to clear and restore the runway and facilities, as well as obtaining certification from Portugal's National Civil Aviation Authority (ANAC), which is highly unlikely given its current abandoned state.
