Which nearby structure to the Louisiana State Arsenal has the insignia of the Louisiana Legion?

The Louisiana State Arsenal itself features the insignia of the Louisiana Legion. This historical structure served significant roles throughout its existence, primarily in military function and support. As an arsenal, it was equipped for the storage and preparation of weaponry, and it holds a connection to the Louisiana Legion, which was an important military organization established during the Civil War.

The other options listed are not associated with the insignia of the Louisiana Legion. The Court of Two Lions is more renowned for its architectural significance and connection to the historic district, while Maison LeMonnier and Maison de Flechier, though notable historic structures, do not have direct ties to the Louisiana Legion in terms of their insignia or military heritage.
