After obtaining the property, Johnson built a fort overlooking the Yadkin River to protect his family and neighbors from attacks during the French and Indian War. Currently, this spot is marked by a monument just south of the Manor House. In 1765, he died and is now buried on the highest hill in the area called Mount Pleasant. In 1809 a simple frame church was erected next to his grave and remains today as one of the park's architectural attractions. Although services are no longer held there, many people are united in marriage at the Mount Pleasant Church each year.
