Horry County’s latest historical marker highlights the historical significance of the Green Sea community.
On Wednesday, November 12, 2025, the Horry County Historic Preservation Commission unveiled the Green Sea Historic Marker at the corner of Green Sea Road and Mitchell Sea Road.
The community dates back to 1784 when a man named William Norton received a land grant for 200 acres, including the area where the marker is located.
By 1787 Norton owned 2,000 acres of land, leading the area to be known as “Norton’s Crossroads.” At the time, the heart of the community consisted of a meeting house and mill.
By the 1850s, the name shifted to “Blanton’s Crossroads” after a post office.
Over time, the community went by several additional names before finally sharing “Green Sea” with the larger township.
“I was amazed when I started doing the history on this place and how much colonial history there is here, and we are in the 250th anniversary of our country's founding,” said Jamie Thompkins of the Horry County Historic Preservation Commission. “I was absolutely astounded that how many people settled here in places like Grassy Bay, Pleasant Meadow, Lake Swamp, you know, in all the colonial records you see those names mentioned.”
This marker is part of the South Carolina Department of Archives and History’s official historic marker program.
It is the goal of the Horry County Historic Preservation Commission to sponsor two of these markers annually.
