Over time, Jacobus acquired more land around the property he already owned in the Bronx. His son, Frederick, received part of this land. Frederick began building a house there in 1748, but he died before the house was completed in 1749. In his will, he included orders to build a family vault. Frederick was the first family member buried in the vault.
The vault served as the family burial ground for the Van Cortlandts until 1888. That year the Van Cortlandt family land, along with the vault, was purchased by the City of New York to be used as a city park. Over the years, particularly in the 1960s, the vault was vandalized with many of the gravestones being removed. The fault can be found on a ridge sitting atop the Parade Ground to the south.
