Limestone is the white rock which can be seen in exposed patches on the hills around the Antrim Coast and in larger deposits at Glenarm where it has been quarried since the late 18th Centuary.
The Limestone industry has had a key influence on the development of Glenarm along the river and harbour;
Limestone has contributed significantly to the Glenarm economy since recent research indicates that at it’s peak 250 people had employment there and their day was regulated by ‘ the company bell’. Company Bell is visable in the limestone courtyard.
while the beautifully restored limestone harbour which now enhances the entrance to Glenarm reflects the decorative qualities of limestone when chipped into building blocks.
The old lime crushing machinery and the red brick chimney remain along the Coast Road as listed structures and relics of this industrial heritage, while a new state of the art processing plant operates at the ‘new demesne quarry ‘ along Munie Road
