About

Sion Mills ward encompasses a largely rural landscape on the outskirts of the Derry City and Strabane District. The area is defined by the River Mourne, which flows through its centre, and is characterised by agricultural land and dispersed residential settlements. The village of Sion Mills itself forms the main population hub within the ward's boundaries.

The village's identity is historically intertwined with the Herdman's linen mill, a large 19th-century complex whose architecture and former workers' housing still shape the community. This industrial heritage sits within a setting of green fields and river walks. The local economy includes farming and smaller enterprises, with the area functioning as a quiet residential zone for the wider district.
