10 Hidden Gems in Buenos Aires: Beyond the Tourist Trail

10 Buenos Aires hidden attractions

1. City Legislature Library

If you are a book lover, there are many hidden gems in Buenos Aires to discover. I am sure you have heard about the iconic El Ateneo Grand Splendid, but there is so much more.

My personal favorite is Esteban Echeverría Public Library, also known as the City Legislature Library. This is such an underrated attraction in Buenos Aires as most tourists just see the building from the outside without a clue what treasures can be found inside.

I am sure that the beautiful wooden details and the massive chandelier will leave you astonished. Also, it counts around 40,000 book copies that are all publicly accessible, although some have been digitized.

This is one of the most beautiful secret spots in Buenos Aires due to its architecture and design, and the best part is that it is free to visit, such as the rest of the palace. Keep in mind that you will have to show your ID and go through a security check (similar to the airport).

2. Basilica of Our Lady Help of Christians and Saint-Charles

Buenos Aires is home to many churches, each hiding remarkable treasures. One of the finest examples is the Basilica of Our Lady Help of Christians and Saint-Charles, located in Almagro.

At first glance, it may seem like just another church, but stepping inside reveals one of the most unique places in Buenos Aires. Dating back to the early 1900s, this basilica features stunning ceiling frescoes, a grand Italian organ, and intricate architectural details.

Founded by the Salesian priests of Don Bosco from Genoa, who began their mission in Argentina in 1875, the church blends several styles. It incorporates Byzantine and Neo-Romanesque influences, with horizontal stripes characteristic of Ligurian design.

For those exploring Buenos Aires off the beaten path, this basilica is a must-visit and stands among the city’s most impressive churches.

3. Parque Lezama and the Russian Orthodox Church of the Holy Trinity

Between the neighborhoods of San Telmo and La Boca, you’ll find Parque Lezama, one of the best non-touristy spots in Buenos Aires. This park offers a peaceful escape from the city crowds, perfect for a walk, a bike ride, or simply relaxing.

As you explore, you’ll come across several statues, an amphitheater, and even a small replica of a Greek temple. On Saturdays, during the San Telmo Fair, the park also fills with market stalls.

Within the park, the Museo Histórico Nacional offers insights into Argentina’s past, showcasing artifacts from the Argentine War of Independence, the May Revolution, and historical daily life.

Overlooking the park is the Russian Orthodox Church of the Holy Trinity, a hidden architectural gem of Buenos Aires. Though lesser-known, it’s worth visiting both inside and out for its stunning design.

At the park’s northwest entrance, you’ll find Bar Británico and Hipopótamo, two bars notables that are among Buenos Aires’ best-kept secrets. These historic cafés in Buenos Aires are perfect for experiencing the city’s traditional bar culture.

4. St. Catalina de Siena Church

Just a few meters from the bustling Florida Street, you’ll find Santa Catalina de Siena Church, one of Buenos Aires’ most fascinating yet lesser-known religious sites.

Dedicated to Saint Catherine of Siena, the patroness of the Italian city, this church was home to the city’s first monastery for women. Dating back to 1717, it is one of the oldest and most historically significant religious buildings in Buenos Aires.

While the church itself has a simple and understated design, its courtyard is the true highlight, especially in spring, when the garden is in full bloom. The colonial architecture, lush greenery, and peaceful atmosphere make it a perfect retreat from the city’s hectic streets, just steps away.

Today, the monastery’s courtyard houses a café and restaurant, offering a unique setting unlike anywhere else in Buenos Aires. Despite its charm and history, Santa Catalina de Siena remains an underrated landmark that deserves more recognition.

5. Casa Ezeiza and other hidden gems in San Telmo

Even though San Telmo is featured in nearly every Buenos Aires travel guide, the neighborhood is full of hidden gems that many tourists overlook.

One of the most charming spots is Casa Ezeiza, a historic house with a beautiful courtyard filled with boutiques, artisan shops, and even tango and language schools. Another must-see is Casa Mínima, the narrowest house in Buenos Aires.

Despite San Telmo’s many bars, cafés, and restaurants, a few spots still offer a truly authentic Buenos Aires experience. One of my favorites is Café de las Máscaras, a cozy café with an artistic atmosphere and a courtyard surrounded by lush greenery. 

Lastly, the Danish Church is one of San Telmo’s best-kept secrets. Its architecture transports you straight to Denmark, and it reminds me of the churches back home in Riga, making it a special find in the heart of Buenos Aires.

6. Galerías Pacífico

If you love shopping, you’ll enjoy Galerías Pacífico. But architecture lovers shouldn’t miss it either.

This mural-filled shopping mall offers tax-free shopping and serves as a hub for local tour operators. Its main hall is the real highlight, featuring a round square surrounded by columns and frescoes that make it a work of art.

Around Christmas, the hall transforms with one of Buenos Aires’ favorite Christmas trees. If you’re searching for hidden gems and great photo spots, don’t miss Galerías Pacífico.

7. Parrilla 1880

Parrilla 1880 is probably my favorite steakhouse in Buenos Aires. This secret Buenos Aires spot was recommended by a local, and I totally get the hype.

Located near Parque Lezama, this retro-style restaurant has vintage posters on the walls, reminiscent of Buenos Aires’ historic cafés. But the real star here is the succulent meat.

My favorite cut is ojo de bife, but the bife de lomo is also outstanding and a must try Argentinian dish in Buenos Aires. Pair your meal with provoleta and homemade chimichurri for a true local experience. 

The service is warm and welcoming. After our second visit, they treated us like friends. For the quality of the meat, 1880 is incredibly well-priced, making it a fun and delicious hidden gem in Buenos Aires.

8. Mural Frida Kahlo

Palermo is home to countless fantastic street artworks, and while some are very famous and popular some others can be considered real hidden gems in Buenos Aires. 

I am referring specifically to the Mural Frida Kahlo. Since it is located a little further from the main attractions and bars of Palermo, this mural tends to be left behind by the majority of people. 

Frida Kahlo was a Mexican painter and one of the most important artists in Latin American culture. She became famous, especially for her self-portraits, and was inspired by the local popular culture. 

This splendid mural is inspired by one of her self-portraits but with a modern twist. The Kahlo’s elements, like the vivid colors, are well displayed.

The mural is located right in front of the flea market and the Parque Mafalda, another interesting spot where to see street art dedicated to this famous Argentinian character.

9. Salón 1923

While Barolo Palace is one of the top attractions in Buenos Aires, not everyone knows about Salón 1923, located on the 16th floor of the palace. Salón 1923 serves fantastic aperitifs & cocktails and offers one of the best secret views of Buenos Aires.

If you love photography, visit at sunset to capture the Congreso Nacional bathed in golden light. Preferably with a cocktail in hand. Alternatively, enjoy a relaxing brunch with stunning Buenos Aires views.

Accessing Salón 1923 is not easy. The space is small and loved by locals, so a reservation is a must. Don’t leave it for the last minute, though!

10. Le Jardin Secret

Buenos Aires has many places with a Parisian touch, but one of the best-kept secrets is Le Jardin Secret – Gontran Cherrier, a French-style café inside the Alianza Francesa language school on Av. Córdoba 946.

Once you step in, you will have to go to the first floor to find this cafe. The cafe is a wonderful example of French design and architecture and will make you feel like in Paris.

Their canelé and macarons are delicious, though the pain au chocolat and croissants don’t quite match the Parisian originals. I also heard their éclairs are worth trying, but by then, I had already indulged in too many sweets. Still, it’s a perfect spot for a coffee break or afternoon snack.
