Which city in Virginia is known for its role in the Civil War with significant battle sites?

The city known for its significant role in the Civil War, particularly with notable battle sites, is Manassas. This city is famously associated with the First and Second Battles of Bull Run, which were pivotal early battles in the Civil War, occurring in 1861 and 1862 respectively. These battles not only involved large troop engagements but also showcased the fierce nature of the conflict, illustrating key tactical approaches and the stakes involved in the struggle between Union and Confederate forces.

Other cities like Richmond served as the capital of the Confederacy and played a crucial administrative and logistical role, while Norfolk was important due to its naval base and shipbuilding facilities. Virginia Beach is primarily known as a resort area and did not have the same military significance during the Civil War as Manassas did. Therefore, Manassas stands out specifically for its direct involvement in critical battles, making it the correct answer.
