Pantheon, Paris (must see)

The Panthéon of Paris, originally conceived as a church dedicated to Saint Genevieve, has evolved significantly since its inception. Constructed between 1758 and 1790, it was intended by King Louis XV to house the relics of Paris's patron saint. The structure stands on a historically rich site, previously home to Roman monuments, and underwent numerous transformations, most notably during the French Revolution when it was repurposed as a secular mausoleum.

The Panthéon was designed to combine the lightness of Gothic cathedrals with the classical grandeur admired in Italian architecture. The architecture of the Panthéon is a striking example of early Neoclassicism, dominated by a triple dome, each layer serving both aesthetic and structural purposes. The middle dome features a painted ceiling, while the outer stone-built dome, completed in 1790, was designed to rival the domes of major basilicas in Rome and London. Initially topped with a cross, the dome has seen various symbols over the years, reflective of France's turbulent history.

Inside, the Panthéon hosts the Apotheosis of Saint Genevieve, surrounded by important figures from French royal history and Christianity. Its peristyle and façade mimic a Greek temple, adorned with Corinthian columns and a pediment that celebrates national gratitude towards illustrious figures, reinstated post-Revolution to honor France's great men and women.

The Panthéon also served as the site for Léon Foucault's famous demonstration of the Earth's rotation in 1851, using a pendulum suspended from the central dome—a copy of which remains on display today.

Throughout its history, the Panthéon's role has shifted between religious and national significance. During its time as the revolutionary "Temple of the Nation", it housed the remains of prominent French figures such as Voltaire and Rousseau. Declared a mausoleum for "National Heroes" in the 19th century, other notables like Victor Hugo and Marie Curie found their final resting place here. More recent additions included French resistance heroes, recognizing their roles in World War II.

Today, the Panthéon is a monument to France's past but also a symbol of its enduring values, reflecting the nation's historical journey and its commitment to honoring those who have shaped its cultural and political landscape.
