The town of Bel Air is the hub of Harford County and one of the most vital towns in the state of Maryland. Developed as the county seat in 1780, Bel Air began as an area of about seven blocks by two blocks with a courthouse directly in the center. Today, after tremendous growth, Main Street and the courthouse still lie at the heart of the town. From Bel Air's beginning to its incorporation in 1874 and through the 21st century, growth and change have presented challenges and opportunities for this storybook community.
