Cassilis War Memorial Park is a large public park, featuring a variety of community amenities, including a rodeo ground, tennis courts, barbeque area, and picnic tables. Providing a formal entrance to the park are the memorial gates, which were built in 1935–1936 in honour of those who served in the First World War. The gates are comprised of four red-brick pillars, joined with iron gates. Each pillar is topped with a concrete block, which is embellished with a concrete sword. The two central pillars are taller than those on the left and right sides and feature brass plaques inscribed with an honour roll for the war. At the bottom of the roll on the right-hand side pillar is an additional dedication for those who served in the Second World War, Korea, and Vietnam. The land for the park was gifted by the Busby family, who were the first European settler family to take up land in Cassilis. It was previously known as Cassilis Park, until 1935 when it was renamed as a war memorial (Mudgee Guardian and North-Western Representative, 11 August 1935). Commemorative services for Anzac Day are held each year at the gates, and along the road leading to the park is the Cassilis Memorial Avenue.
