In which year did Congress vote to replace the dome of the Capitol?

The dome of the Capitol was a significant architectural feature, and Congress made a pivotal decision regarding its replacement in 1855. The need for a new dome arose due to the original structure's limitations and the desire for a stronger, more visually impactful design that would reflect the growing stature of the U.S. government. This replacement initiative marked a key moment in the Capitol's architectural history, culminating in the magnificent dome we see today, which was formally completed in the early 1860s.

The timeline surrounding this decision is crucial, as the original dome was unfinished, and the replacement became essential to symbolize the nation's stability and progress. Understanding the context of the 1855 vote reveals how the Capitol's design evolved to represent a more unified and powerful government, especially during the turbulent times leading up to and including the Civil War.
