The Corridor of Oaks in Faulconbridge, Blue Mountains NSW, is a unique memorial where every Australian Prime Minister, or a close relative, has planted an oak tree since Federation. Located in Jackson Park near Sir Henry Parkes' grave, the avenue was conceived by Joseph Jackson MLA in 1934 to symbolise national leadership and honour the Father of Federation. Today, the shaded path features 29 oaks, plaques, statues, and picnic spots, making it a favourite for history enthusiasts and families. Its living legacy continues to grow, reflecting the nation's political history. https://en.wikipedia.org/wiki/Prime_Ministers%27_Corridor_of_Oaks
