5 Best Sights in The Latin Quarter, Paris

This Roman amphitheater, designed as a theater and circus, was almost completely destroyed by barbarians in AD 280. The site was rediscovered in 1869, and you can still see part of the stage and tiered seating. Along with the remains of the baths at Cluny, the arena constitutes rare evidence of the powerful Roman city of Lutetia that flourished on the Rive Gauche in the 3rd century. Today it's a favorite spot for picnicking, pickup soccer, or boules.

Crime buffs will enjoy this museum hidden on the second floor of the 5e arrondissement's police station. Although the exhibits are in French only, the photographs, letters, drawings, and memorabilia pertaining to some of the city's most sensational crimes are easy enough to follow. Among the 2,000-odd relics you'll find a guillotine, old uniforms, and remnants of the World War II occupation—including what's left of a firing post, German machine guns, and the star insignias worn by Jews.

This square was named for Gabriel Davioud's grandiose 1860 fountain sculpture of St. Michael vanquishing Satan—a loaded political gesture from Napoléon III's go-to guy, Baron Haussmann, who hoped St-Michel would quell the Revolutionary fervor of the neighborhood. The fountain is often used as a meeting point for both local students and young tourists.

This jewel box of a church has been visited by several popes paying tribute to Ste-Geneviève (the patron saint of Paris), who was buried here before Revolutionaries burned her remains. Built on the ruins of a 6th-century abbey founded by Clovis, the first king of the Franks, it has a unique combination of Gothic, Renaissance, and early Baroque elements, which adds a certain warmth that is lacking in other Parisian churches of pure Gothic style. Here you'll find the only rood screen left in the city—an ornate 16th-century masterwork of carved stone spanning the nave like a bridge, with a spiral staircase on either side. Observe the organ (dating from 1631, it is the city's oldest), the ornate wood-carved pulpit, and the marker in the floor near the entrance that commemorates an archbishop of Paris who was stabbed to death here by a defrocked priest in 1857. Occasional guided tours (in French) are free, but a small offering is appreciated; call for exact times.

This tiny shrine in the shadow of Notre-Dame is one of the three oldest churches in Paris. Founded in 1045, it became a meeting place for university students in the 12th century and was Dante's church of choice when he was in town writing his Divine Comedy. Today's structure dates mostly from the 1600s, but keep an eye out for older pillars, which crawl with carvings of demons. You can maximize your time inside by attending one of the classical or gospel concerts frequently held here. Alternately, go outside and simply perch on a bench in the lovely garden and gaze across the Seine at the newly restored Notre Dame.
