Rothesay Common is a park that has played an important role in the Rothesay community since its inception. Originally located in the physical center of Rothesay, it is currently found on the town's west side due to expansion. The land was formerly owned by the Robertson family, one of the first families to settle in Rothesay. The two sisters of the family, Grace E. Nichols and Mary Robertson, were considered the cultural and social leaders of the new community. They used the land as a cow pasture until 1934, when they sold it to the town under the condition that it would be turned into a public park. Since then, the Rothesay Common has been the site of a range of social and cultural activities in the community, including concerts, fairs, and ceremonies.

The park also contains a valuable reminder of the town's role in Canada's military endeavors. Located in the heart of the park is the Cenotaph, a memorial to the Rothesay soldiers who died during World War I, World War II, and the Korean War. The monument consists of a stone cross surrounded by three flagpoles.
