Jay County

Jay County is an administrative division in eastern Indiana covering agricultural land where the Salamonie River winds through several townships and settlements. The county comprises multiple communities and includes the city of Portland, which serves as its main administrative hub.

The Indiana State Legislature established the county in 1835, naming it after John Jay, who served as the first Chief Justice of the United States. The area subsequently developed as an agricultural center and attracted many settlers of German descent.

German heritage runs deep through family traditions and community celebrations that remain visible in how residents gather and mark important occasions together.

The county courthouse in Portland serves as the administrative center where visitors can find information and services. A car is helpful for traveling between communities, as the area is spread across multiple townships.

A direct communication system was activated in 2023 to help residents quickly find support during emergencies and after severe storms. This connection between local emergency officials and residents has improved how information reaches people who need assistance.
