Who says you have to leave the city to go hiking? Today, I propose a day of urban trekking (city-trekking or low-intensity steady-state cardio - LISS). An active yet deeply contemplative journey designed to rediscover the history, architecture, and daily pulse of three emblematic neighborhoods in the Autonomous City of Buenos Aires: Palermo, Villa Crespo, and Caballito.
The Route: Step by Step
• Starting and Ending Point: Intersection of Av. Santa Fe and Av. Scalabrini Ortiz (Circular route).
• The Outbound Journey: We begin our walk straight down the vibrant Av. Scalabrini Ortiz. Upon crossing Av. Córdoba, we officially enter the tango-paced streets of Villa Crespo.
• Continuing On: We keep moving forward until turning onto Av. Warnes, which guides us directly toward our green oasis. Crossing Av. Ángel Gallardo, we formally enter the Caballito neighborhood and come face-to-face with our main destination: Parque Centenario. Here, we will complete two full laps around its perimeter before heading back to our starting point.
Landmark Guide: History and Architecture Around the Park
During our two reconnaissance laps around the park and its surroundings, we will stop at these milestones of great heritage and cultural value:
1. Parque Centenario
Designed by the famous landscape architect Carlos Thays and inaugurated in 1910 to commemorate the centennial of the May Revolution. This green lung of Caballito stands out for its perfect radiocentric design and its beautiful central artificial lake, establishing itself as one of the most important recreational hubs in the commune.

2. Bernardino Rivadavia Natural Sciences Argentine Museum
One of the most significant natural science museums in Latin America. Originally founded through the initiative of Bernardino Rivadavia in 1812, its imposing current building blends an eclectic style with ornamentations of local flora and fauna carved in stone and ironwork.
• Dinosaur replicas in the gardens: Visible from the outside and on the grounds, these life-sized fiberglass sculptures of species such as the Tyrannosaurus rex, Triceratops, ankylosaurs, and various herbivores are accompanied by educational scientific signage.
• Prehistoric megafauna: The outdoor tour also features skeleton reproductions of the megafauna that once inhabited the Pampas region. A striking and dynamic sculpture recreating a fight between two saber-toothed cats (Smilodon populator) stands out.
3. Luis Pasteur Zoonosis Institute
Located within the park grounds, this national reference public institution was founded at the end of the 19th century. Its work is crucial for public health, focusing on the research, prevention, diagnosis, and treatment of diseases transmitted from animals to humans (zoonosis), as well as providing vaccination and epidemiological control services.
4. Pedro Mallo Central Naval Hospital (Naval Building)
Located across from the park on Av. Patricias Argentinas. Designed by the renowned architect Clorindo Testa alongside Lacarra and Marré (inaugurated in 1981), it is a masterpiece of Argentine modern and brutalist architecture. Its concrete structure explicitly emulates the silhouette of a large transatlantic ocean liner, complete with circular porthole-style windows.
5. Astronomical Observatory (Argentine Association of Friends of Astronomy)
Founded in 1929, this historic civil institution has its headquarters and observatory inside the park. With its iconic domes and telescopes (both historic and modern), it is a beacon for scientific outreach, offering courses, workshops, and organizing guided night visits.
6. Parque Centenario Book Fair
A classic of Buenos Aires culture. Its permanent stalls on the outer ring of the park form one of the city's most traditional spots for book exchanges, specializing in used books, out-of-print magazines, comic books, school textbooks, and collectible literature.
7. Parque Centenario Flagpole
An imposing, patriotic sculptural structure. Its ornamental base, covered with artistic reliefs and decorative majolica tiles, pays tribute to major milestones and allegories of national history and Argentine identity.
8. Marie Curie Oncology Hospital
Accuracy Note: Located right in front of the park (on Patricias Argentinas Street), this public health center specializes in oncology treatments (often locally associated with the Ángel H. Roffo Oncology Institute). It stands out for its historic pavilion-style architecture, dedicated to radiotherapy and comprehensive cancer care.
9. Our Lady of Sorrows Parish and Shrine
• The Parish: Located facing the park, at the intersection of Av. Díaz Vélez and Campichuelo, stands this sanctuary of imposing Neo-Gothic architecture inaugurated in 1942.You can find more details about its architecture and parish history on the Iglesias de Buenos Aires website - Parroquia de los Dolores: https://baiglesias.com/parroquia-y-santuario-nuestra-senora-de-los-dolores/
• The Park Shrine: Inside the park itself, mounted on an exposed brick monolith, lies the Our Lady of Sorrows Shrine made of majolica tiles. This space serves as a strong community anchor, especially in mid-September during the neighborhood's Patronal Feasts, when the faithful hold processions around the image inside the park.
10. Mural. A piece created by the Pinta Argentina project, led by Victoria Ferreyra, depicting a red-haired figure reading a book surrounded by blue and yellow silhouettes symbolizing the embrace between street art and daily life.
Travel Log: Nostalgia, Changes, and a Personal Outlook
Urban trekking also means sharpening your eye to spot the details hidden by daily haste, and confronting the present with our own memories of public spaces.
The corner of neglect and the dismantled fair
When passing by Parque Centenario, it is impossible to miss a closed iron gate that almost goes unnoticed. Behind it, the overgrown grass betrays signs of neglect. A ramp at this entrance connects to a large paved area that functions as a parking lot.
Nowadays, only the traditional official fairs persist in the park (the book fair and the craft fair). However, this paved area used to host an informal—or semi-formal—fair popularly known as the feria de los manteros (street vendors' fair), which was permanently dismantled by the City Government in August 2024.
Memories of a weekend "combo"
Before the pandemic, I used to frequent this loop quite a bit as a perfect weekend plan. My "combo" would start at Parque Rivadavia in Caballito. There, I would browse its famous coin and stamp collecting fair, and sometimes the book and sticker trading fairs.
After that first stop, I would walk down to the manteros fair at Parque Centenario. It was a chaotic universe where, amid a lot of "junk," treasures would always appear. My main interest was unique antiques and coins. Although it lacked the specialized nature and collectible pieces of the Parque Rivadavia fair, you could find plenty of national coins—especially common circulation commemorative editions—on the blankets of Centenario at a notably lower cost. For others, the draw was clothing, toys, or vintage tech gear. Today, seeing that silent, closed lot brings back nostalgia for those walks spent searching and haggling.
Conclusion
This urban trekking circuit shows us that the City of Buenos Aires is an open-air museum. In a single walking tour, we connect the commercial pulse of Palermo, the identity of Villa Crespo, and the green, historic heart of Caballito.
Put on a good pair of sneakers, pack your mate thermos, and head out to walk the city with the eyes of an explorer.
