The residents of Sant Climent Sescebes, a small town of about 700 inhabitants in the Alt Empordà region, are accustomed to the sounds of gunfire and explosions in the distance. Less than a kilometer away lies the Spanish army's training base, the only one in Catalonia where soldiers conduct live-fire exercises and maneuvers with explosives. Every week, the soldiers carry out exercises with live ammunition, and occasionally, other forces such as the Civil Guard, the Mossos d'Esquadra (Catalan police), or, in recent months, even elite squadrons of the Ukrainian army, also come to the 1,300-hectare training ground.

Xasteros House, designed in 1969 by the visionary Greek architect Nikolaos Xasteros, arrived at the Terra Remota winery in Sant Climent Sescebes in May 2023 and quickly became the centerpiece of the 54-hectare estate. The winery's owners, French couple Emma and Marc Bournazeau, are keen on architecture, and there's always an experimental house on display on their estate. Xasteros House is a work inspired by the space age—which is why it's also known as "the UFO house," as it evokes a spaceship—and is one of the jewels of 20th-century prefabricated architecture. Until Brad Pitt acquired it in the middle of last year, it was owned by French collector and gallery owner Clément Cividino, who rescued it from a town near Athens and restored it. Apparently, the discovery of the Xasteros House was something "uncommon" that a group of Greek architects discovered about seventeen years ago in the middle of a forest in Athens, where the structure was abandoned.
