4 Best Sights in Mexico City, Mexico

These infectiously festive plazas function as Coyoacán's zócalo and are barely separated from each other by a narrow, slow-moving street. The Jardín, with its shading trees, an oft-photographed fountain with two snarling coyotes, and a fringe of lively patio bars and restaurants (of varying culinary repute), is the more commercial—but also arguably the prettier—of the two.

The larger Plaza Hidalgo hosts children's fairs, musical and dance performances, clowns, bubble blowers, and cotton candy and balloon sellers, especially on weekends and holidays. It's anchored by an ornate old bandstand and the impressive Parroquia de San Juan Bautista, one of the first churches to be built in New Spain. Each afternoon of September 15, before the crowds become suffocating at nightfall, these delightful plazas are perhaps the best place in the capital to enjoy Independence Day celebrations. More recently, they've become the city's must-go for Día de Muertos in early November, with throngs of people of all ages cavorting about in costume and face paint. Both plazas are filled with landscaped courtyards, public art installations, and dozens of park benches, and they're a memorable destination for people-watching. You'll see passersby of all ages and backgrounds, from multigenerational families and young couples of all sexual orientations cuddling, kissing, and holding hands, to tourists from all over the world, and locals walking their dogs (who are often gussied up in sweaters and bows).

This picturesque plaza lined with palatial 18th- and 19th-century homes as well as a number of galleries, boutiques, and restaurants constitutes the heart of San Ángel. On the north side of the plaza, the excellent arts-and-crafts market Bazaar Sábado is held all day Saturday, and just west up Calle Benito Juarez there's an additional covered market on weekends where you can find cheaper knickknacks and goods. Continue a block down the hill along shop-lined Calle Madero to reach Plaza del Carmen, a smaller park with pathways and benches where still more artists sell their works on Saturday. A memorial plaque on Plaza San Jacinto's west side lists the names of about 50 Irish soldiers from St. Patrick's Battalion who helped Mexico during the "unjust North American invasion" of 1847. These men had been enticed to desert the ranks of U.S. General Zachary Taylor by appeals to the historic and religious ties between Spain and Ireland, siding with the Mexicans in the Mexican-American War. Following their capture by U.S. forces, all were hanged (16 of them on Plaza San Jacinto).

Zócalo literally means "pedestal" or "base"; in the mid-19th century, an independence monument was planned for the square, but only the base was built. The term stuck, however, and now the word "zócalo" is applied to the main plazas in many Mexican cities. Mexico City's Zócalo (because it's the original, it's always capitalized) is used for government rallies, protests, sit-ins, and festive events. It's the focal point for Independence Day celebrations on the eve of September 16 and is a maze of lights, tinsel, and traders during the Christmas season. Flag-raising and -lowering ceremonies take place here in the early morning and late afternoon.

Formally called the Plaza de la Constitución, the enormous paved square, the largest in the Western Hemisphere, occupies the site of the ceremonial center of Tenochtitlán, the capital of the Aztec empire, which once comprised 78 buildings. From the early 18th century until the mid-1900s, the plaza housed a market known as El Parián, specializing in luxury goods imported from Asia on the Manila Galleons, Spanish trading ships that crossed the Pacific from the Philippines to Acapulco. And while the Zócalo has seen the rise and fall of governments and movements for seven centuries, many of the rust-red facades that ring the plaza today—save for the first two floors of the emblematic Palacio Nacional and the Cathedral—were only added in the early 20th century, built in the neo-colonial style in fashion following the Revolution.

The Zócalo is the heart of the Centro Histórico, and many of the neighborhood's sights are on the plaza's borders or just a few short blocks away. Even as the Mexican economy has gradually begun to centralize in recent years, the Zócalo remains the indisputable center of the nation.
