It was rebuilt north of Darien until the present day building was completed on Vernon Square in 1879.

It was considered a part of the healing process and reunification between the north and south after the Civil war ended.

In 1863 during the American Civil War, the church was burned down (along with the rest of the town, which was pillaged and looted) by Union troops commanded by Colonel Robert Gould Shaw.

Shaw was later killed in action during an attack on Fort Wagner in South Carolina.

About a year after the new church was built members of the parish raised the money to purchase a lot where the Bank of Darien once stood on Vernon Square, not far from where the town was invaded during the Civil War and began to construct the present-day St. Andrew's church building.
