Troia occupies a narrow peninsula that extends northward along the Atlantic coast, separating the Sado River estuary from the open ocean south of Lisbon. Robert Trent Jones designed the course in the late 1970s as part of a resort development on this distinctive spit of land, where the routing takes advantage of the dual water presence and the coastal pine forest that characterizes much of the Portuguese shoreline. The layout moves through corridors of umbrella pine and maritime vegetation, with several holes playing near or alongside the estuary waters. The course reflects Jones's characteristic design approach from this period, with generous fairways, strategically placed bunkers, and greens that reward accurate approach play. The peninsula setting provides ocean breezes that influence club selection and shot-making throughout the round. The flatter terrain of the sandbar allows for relatively walkable golf, though the length and prevailing wind can present a test for players of varying abilities. Troia serves as the centerpiece of the resort complex, which includes hotel accommodations and beach access along the Atlantic side of the peninsula. The location offers views across the estuary toward the Arrábida mountain range and provides a retreat from Lisbon, accessible by ferry or road via the southern route around the Sado. The course has hosted Portuguese national championships and remains a destination for golfers visiting the Lisbon region who seek coastal golf in a relatively secluded setting.
