When the Civil War ended, Fort Sumter was in ruins.
The U.S. Army worked to restore it as a useful military installation.
The damaged walls were re-leveled to a lower height and partially rebuilt.
The third tier of gun emplacements was removed.
Eleven of the original first-tier gun rooms were restored with 100-pounder Parrott rifles.

From 1876 to 1897, Fort Sumter was used only as an unmanned lighthouse station.
The start of the Spanish–American War prompted renewed interest in its military use and reconstruction commenced on the facilities that had further eroded over time.
A new massive concrete blockhouse-style installation was built in 1898 inside the original walls, armed with two 12-inch M1888 guns, one on a disappearing carriage.
Named "Battery Huger" in honor of Revolutionary War General Isaac Huger, it never saw combat.
This battery was deactivated in 1947, and in 1948 the fort became Fort Sumter National Monument under the control of the National Park Service.

One hundred and forty-seven years after it was sent, a rolled up telegraphic message was found and eventually given to a museum in Charleston, S.C. The telegram was dated April 14, 1861 from the Governor of South Carolina to Gazaway Bugg Lamar in New York, reading in part:
Fort Sumter surrendered yesterday after we had set all on fire... F.W. Pickens
In 1966, the site was listed on the National Register of Historic Places.
The Civil War Trust (a division of the American Battlefield Trust) and its partners have acquired and preserved 0.23 acres (0.00093 km²) of historic land related to the battles at Fort Sumter.
