Planted in 1919, The Grove of Remembrance (or Memorial Grove Oaks) honors those who fought in World War I. Two markers stand at the entrance of the thicket, one showing dedication information and the other displaying a map of the woodland area. One tree was planted for every state, the city of Baltimore and Woodrow Wilson. As the years went by more trees were planted marking each subsequent American War. It is said to be the oldest living memorial in the United States.
