Overview

Armstrong County is a county located in Pennsylvania, in the western portion of the state. It is a predominantly rural area of small towns, farmland and river valleys. According to the 2010 census, the county had a population of approximately 65,263. The county seat is Kittanning, a historic borough that serves as the local seat of government and services.

History and development

The county was established around 1800 during the early years of Pennsylvania’s expansion west of the Allegheny Mountains. Its development reflected common regional themes: settlement along rivers, agriculture on fertile valleys, and later industrial activity tied to coal, oil and small-scale manufacturing. Over time many communities evolved from river trading posts to modern small towns while preserving historic downtowns and civic buildings.

Geography and recreation

Armstrong County features rolling hills, wooded ridges and streams that drain into the Allegheny River. Outdoor recreation is important locally: state parks, reservoirs and public lands support boating, fishing, hiking and hunting. Crooked Creek State Park and other natural areas provide trails, campgrounds and picnic facilities for residents and visitors.

Economy and government

The local economy combines agriculture, energy production (historically coal, oil and natural gas), light manufacturing and services. Many residents commute to larger regional centers for work. County government is centered in Kittanning and operates through elected officials and departments that oversee courts, public safety, roads and social services.

Communities and notable facts

Armstrong County contains a number of boroughs and townships, each with its own character — from riverfront communities to agricultural town centers.
