Portsmouth Country Club occupies rolling terrain in Greenland, New Hampshire, a small town situated between Portsmouth and the Massachusetts border in the Seacoast region. Robert Trent Jones Sr. designed the course, which opened in the 1950s during the architect's prolific period of American course construction. The layout reflects Jones's characteristic design principles from that era: strategic bunkering, elevated greens with pronounced contours, and an emphasis on length and accuracy from the tee. The property features mature tree-lined fairways and elevation changes that provide both visual interest and strategic variety across the eighteen holes. The course routing takes advantage of the natural topography, with several holes playing uphill or downhill and others moving through more level corridors. Jones incorporated water hazards and positioned bunkers to challenge approach shots and demand precise iron play. The greens typically feature the bold undulations and multi-tiered surfaces that became signatures of his design work, rewarding well-placed tee shots that open favorable angles into the putting surfaces. Portsmouth Country Club serves as a private facility for its membership in the Seacoast New Hampshire region. The club provides a traditional country club experience with both golf and social amenities. The course has hosted various regional amateur competitions over the decades, serving as a competitive venue for New Hampshire and New England golf events. The layout remains a representative example of Robert Trent Jones Sr.'s mid-century design approach adapted to New England's rolling landscape.
