Which structure is located at the City Park entrance at the end of Esplanade Avenue?

The structure located at the City Park entrance at the end of Esplanade Avenue is indeed the General P.G.T. Beauregard statue. This statue honors General Pierre Gustave Toutant Beauregard, a prominent Confederate general during the American Civil War. The statue is situated in a location that reflects both historical significance and a sense of place within the landscape of New Orleans.

The General Beauregard statue serves as a reminder of the city's complex past and its many historical figures. It is part of a broader narrative in New Orleans that includes a mix of cultural and historical monuments throughout the city, often provoking discussion and thought regarding their contexts.

Other options may refer to different historical figures or cultural aspects of New Orleans, but they do not mark the specific entrance to City Park as effectively as the statue of Beauregard does. Each of those other choices represents significant elements of New Orleans history but is located elsewhere and serves different commemorative purposes.
