The significant restoration completed in National Statuary Hall in 1976 involved returning the space to its 1823 appearance. This restoration was part of the celebration of the United States Bicentennial and aimed to reflect the historical integrity of the Hall as it would have appeared during an important period in American history.

In 1823, National Statuary Hall was used as the meeting chamber for the House of Representatives, and the restoration focused on the architectural features and decorative elements that characterized that time, including the use of columns and a more classic design in line with the Federal style prevalent in early 19th-century America.

This choice highlights the importance of preserving historical contexts and aesthetics, ensuring that visitors can experience the Hall as a fundamental site in the nation's legislative history. The other options either refer to incorrect periods that do not align with the focus of this restoration or suggest a modern artistic approach that was not part of the aims during the Bicentennial restoration.
