Two rooms that stand out are the decoration of the Reception Hall and the sculptures in the Patio de los Leones. The Reception Hall is on the second floor and designed to imitate the splendor of similar halls in Europe. It is profusely decorated with precious metal and crystal ornaments as well as allegorical murals dedicated to themes such as science, the arts, liberty, history, work and progress. The work devoted to the concept of progress subdivides into four themes of force, justice, wisdom and wealth. This hall became the preferred place for President Porfirio Díaz to perform public declarations and receive dignitaries from abroad. Like the rest of the building the Patio of the Liones synthesizes a number of different architectural styles. The two primary styles seen here are Classic and Gothic with other styles introduced in the forms of sculptures, lighting and sculpted stonework. In the center is a large semicircular staircase to the upper floors.
