The City of North Charleston recently featured a writeup on Park Circle's inspiration.
Ebenezer Howard developed a love of rural living during the Industrial Revolution. He planned a community that would offer plenty of residential, industrial and agricultural areas for balance. In the center, he felt, should be a garden with six avenues radiating from a circle. A residential ring would be circled by an industrial ring, then a ring of open land.
His initial garden city idea would house 32,000 people on 6,000 acres and would be self-sufficient. Once such a city became full, another would be created. He explained his idea in an 1898 book called "Tomorrow: A Peaceful Path to Social Reform" in which he laid out his vision.
A brief 14 years later, The North Charleston Corp. was created to build such a community. Park Circle remains as an homage to Howard's vision.
